+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is

+ % Such a package is    natbib.sty   by Patrick W. Daly
+ % The form of the \bibitem entries is
+ %   \bibitem[Jones et al.(1990)]{key}...
+ %   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists

+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must

+ % The \cite command functions as follows:

+%  *******************************************************************
+%  *         TABLES AND FIGURES    {extensions from AGU macros       *
+%  *******************************************************************
+
+% Additions and adjustments for tables and figures.
+
+% Footnotes for tables are to be identified with lower case alphabetics,
+% rather than numeric.  \tablenotemark and \tablenotetext commands are
+% provided analogous to \footnotemark and \footnotetext, but with the
+% identifier *required*, like \altaffilmark and \altaffiltext.  The
+% \tablenotetext must be specified before the \end{table}, since
+% \end{table} displays it.
+%
+%     \tablenotemark{TAG LETTER(S)}
+%     \tablenotetext{ALPHA TAG}{TEXT}
+%
+% Note that TAG LETTER == ALPHA TAG for corresponding text.  It is the
+% responsibility of the author to get the correspondence correct.
+%
+% The table footnotes are coupled to the table in which they occur, rather
+% than being associated with a particular page, and they are printed with
+% the table (relatively close to the caption) instead of appearing at the
+% extreme bottom of the page.  This is done to ensure that the notes wind
+% up on the same page as the table, since tables are floats and can migrate
+% from one page to another.  There is the additional benefit that the notes
+% are unambiguously attached to the proper table, which is what is required
+% in the event that the editorial requirement of one table only per page
+% is ever changed to permit several tables per page.
+%
+% Footnotes are NOT supported for figures.
+
+\def\tablenotemark#1{\rlap{$^{\rm #1}$}}
+
+% The \tablenotetext command buffers the table note text and the "proper"
+% tablenote formatting information in a token buffer.  The tablenotes are
+% dispensed into the vertical page list by \spew at tblnotes, which is
+% executed by \end{table}.  Note that certain "global" tablenote formatting
+% details are handled by \spew at tblnotes, which also clears the tblnote list.
+% Praise and honor are due to Kresten Krab Thorup (krab at iesd.auc.dk) for
+% posting ftn.sty to the Usenet, from which I drew the technique.

+%  ********************************************************
+
+% Plano tables are camera-ready pages that are included in a typeset
+% article the same way as line drawings, graphs, and other camera-ready
+% art, i.e., as "planographic" figures.  There are desirable properties
+% for a formatter to have that are somewhat above and beyond LaTeX'x
+% tabular environment that would facilitate the creation of such tables.
+% Among these are breaking long tables across pages, using footnotes
+% in a table, specifying comments and references for tables, etc.
+%
+% What follows was inspired by supertab.sty by Theo Jurriens, 1988.
+
+% Commands for identifying table elements in a consistent way.  Observe
+% that the formatting is embedded in the macro definitions so that the
+% author doesn't need to be concerned about stylistic nuances.
+%

+% Calculate the number of tabular rows that will fit in the body of the
+% table.  The height of the table body and the number of lines are
+% calculated thus:
+%
+%     bodyheight = \textheight * (1 - \pt at headfrac)
+%     \pt at nlines = bodyheight / (\arraystretch * \baselineskip)
+%
+% The row height can be seen to be valid algebraically if one examines the
+% definitions for \strutbox, \@setstrut, and \@array.  I could eliminate
+% this calculation, as well as its attendant parameters, if it were possible
+% to determine the accumulated height of the \halign box as TeX goes along.

+% Define \pt at tabular, a ripoff of \@tabular but with \leavevmode removed
+% so tabular box can be set with \setbox.  I do this so that table notes
+% can be set to natural width of table, if desired.  Also, set \@acol
+% to \@ptabacol, which is called when building the preamble for the
+% \halign (assuming the first column format specification is "l", which
+% it should be for ApJ tables) so that \tabskip within the table is set
+% to \fill.  This permits us to toggle between natural and fixed-width
+% tables without requiring the user to change markup.  Note that by
+% forcing \tabskip always to be \fill, I pretty well nullify any
+% @{\hspace} commands the user puts in the template, but this environment
+% is for people who don't want to think about that sort of stuff anyway.

+% For AGU compatability use a {references} environment
+% It is not necessary to use the thebibliography environment.  This style
+% defines a references environment that simply sets off the list of references
+% and adjusts spacing parameters.  It is not possible to use \bibitems
+% within the references environment.  (The \reference command cannot be
+% shortened to \ref; \ref is used in vanilla LaTeX for cross-referencing.)
+%
+%    \begin{references}
+%    \reference <bibliographic data>
+%    \end{references}
+%
+%    \markcite{TEXT}
+%
+% Observe that the bibliographic data supplied by the author must also
+% conform to the standards of the journal.  I have elected not to burden
+% authors with tedious LaTeX commands which would require many curly braces
+% to delimit the bibliographic fields because many of the journals I have
+% targeted in this project have agreed to reduce typographic overhead (bolding,
+% italicizing, etc.) in reference lists.  (See Abt's editorial in ApJ 357.)
+% It is the responsibility of the author to get these fields in the proper
+% order with the correct punctuation; the information will be typeset as is,
+% i.e., in roman with no size or style changes.
+%
+% Macros are provided for many of the oft-referenced journals so that authors
+% may use the LaTeX names rather than having to look up a particular journal's
+% specific abbreviation.  In principle, all the journals should be using the
+% same abbreviations, too, but I anticipate some changes in the specific
+% abbreviations before a set is finally settled on.  As long as these macros
+% are kept up to date, authors need not be concerned about such editorial
+% changes.
+%
+% Corresponding with the non-BibTeX references environment and \reference
+% command for the reference list is the \markcite command.  This can be
+% used to identify in-text citations; in this case, the author provides
+% the actual citation text as opposed to the symbolic tag.  The use of
+% this is encouraged, even for journals where no special formatting of
+% citation call-outs is required; it is crucial for the future use of
+% on-line browsers.

+\varepsilon_{yy} & = & \partial_y u_y \nonumber \\
+\varepsilon_{zz} & = & \partial_z u_z \nonumber \\

+\varepsilon_{xz} & = & \frac{1}{2} (\partial_x u_z + \partial_z u_x) \,\, , \,\, \varepsilon_{zx} =  \varepsilon_{xz} \nonumber \\
+\varepsilon_{yz} & = & \frac{1}{2} (\partial_y u_z + \partial_z u_y) \,\, , \,\, \varepsilon_{zy} =  \varepsilon_{yz}
+\end{eqnarray}

+\begin{eqnarray}
+\sigma_{xx} & = & (\lambda + 2 \mu) \, \varepsilon_{xx} + \lambda \, \varepsilon_{yy} + \lambda \, \varepsilon_{zz} \nonumber \\

+%\noindent To obtain the CPML form, we just need to replace each spatial derivative with that same derivative multiplied by $1/s$.
+%Thus, with CPML, in differential form in 2D this gives (noting $\frac{\partial^2 u_x}{\partial t^2}$ instead of $-\omega^2 u_x$ for now, even though we perform a Fourier transform,
+%because we will perform an inverse Fourier transform later and thus get the term $\frac{\partial^2 u_x}{\partial t^2}$ back):
+%
+\noindent To obtain the CPML form, we firstly perform a Fourier transform on above equation,
+then replace each spatial derivative with that same derivative multiplied by $1/s$
+to make the plane wave entering into CPML without reflection and decaying exponentially along the x, y, z or in all directions.
+Thus,in differential form in 3D the frequency-domain equation govened the motion in CPML gives:
+%
+\begin{eqnarray}
+\varepsilon_{xx} & = & \frac{1}{s_x}\partial_x u_x \nonumber \\
+\varepsilon_{yy} & = & \frac{1}{s_y}\partial_y u_y \nonumber \\
+\varepsilon_{zz} & = & \frac{1}{s_z}\partial_z u_z \nonumber \\
+\varepsilon_{xy} & = & \frac{1}{2} (\frac{1}{s_x} \partial_x u_y + \frac{1}{s_y} \partial_y u_x) \,\, , \,\, \varepsilon_{yx} =  \varepsilon_{xy} \nonumber \\
+\varepsilon_{xz} & = & \frac{1}{2} (\frac{1}{s_x} \partial_x u_z + \frac{1}{s_z} \partial_z u_x) \,\, , \,\, \varepsilon_{zx} =  \varepsilon_{xz} \nonumber \\
+\varepsilon_{yz} & = & \frac{1}{2} (\frac{1}{s_y} \partial_y u_z + \frac{1}{s_z} \partial_z u_y) \,\, , \,\, \varepsilon_{zy} =  \varepsilon_{yz}

+\noindent In the frequency domain we define:
+\begin{equation}
+\partial_{\tilde{x}} = \frac{1}{s_x}\, \partial_ x,
+\label{diffmapping}
+\end{equation}

+and we know from \cite{KoMa07} that $\partial_x$ is then transformed in the time domain into:
+\begin{equation}
+\partial_{\tilde{x}}= \frac{1}{\kappa_x} \partial_{x}
+- \frac{d_x}{\kappa_x^2} H(t) e^{-(d_x/\kappa_x + \alpha_x)t} * \partial_ x \, .
+\end{equation}
+
+\noindent This means that $\frac{1}{s_x}$ is transformed by inverse Fourier transform into
+$\frac{1}{\kappa_x} - \frac{d_x}{\kappa_x^2} H(t) e^{-(d_x/\kappa_x + \alpha_x)t} *$.

+Here we extended the approach used in \cite{Mat11} to get an stable CPML implementation for spectral element method: Let us multiply the set of equation (6) by $s_x s_y s_z$,
+This will results in a more complex mass matrix on the left-hand side.
+And let us get rid of the source term because there is no source in the PML layers, we have:
+\begin{eqnarray}
+- \rho s_x s_y s_z \omega^2 u_x  & = & s_y s_z \partial_x \sigma_{xx} + s_x s_z \partial_y \sigma_{xy} + s_x s_y \partial_z \sigma_{xz} \nonumber \\

+- \rho s_x s_y s_z \omega^2 u_z  & = & s_y s_z \partial_x \sigma_{zx} + s_x s_z \partial_y \sigma_{zy} + s_x s_y \partial_z \sigma_{zz}
+\end{eqnarray}
+%
+\noindent since $s_y s_z$ does not depend on $x$ ,
+$s_x s_z$ does not depend on $y$ and $s_x s_y$ does not depend on $z$:
+%
+\begin{eqnarray}
+- \rho s_x s_y s_z \omega^2 u_x  & = &  \partial_x (s_y s_z \sigma_{xx}) + \partial_y (s_x s_z \sigma_{xy}) + \partial_z (s_x s_y \sigma_{xz}) \nonumber \\
+- \rho s_x s_y s_z \omega^2 u_y  & = &  \partial_x (s_y s_z \sigma_{yx}) + \partial_y (s_x s_z \sigma_{yy}) + \partial_z (s_x s_y \sigma_{yz}) \nonumber \\

+\end{eqnarray}
+\noindent By inserting the definition of the stress tensor we get:
+\begin{eqnarray}
+- \rho s_x s_y s_z \omega^2 u_x  & = &  \partial_x (s_y s_z ((\lambda + 2 \mu) \, \varepsilon_{xx} + \lambda \, \varepsilon_{yy} + \lambda \, \varepsilon_{zz}))

++ \partial_z (s_x s_y (\lambda \, \varepsilon_{xx} + \lambda \, \varepsilon_{yy} + (\lambda + 2 \mu) \, \varepsilon_{zz}))

+Note that, following \cite{Hug87} equation (9.1.12) page 491, and as also mentioned by \cite{Mat11}, the term $\rho \, A_1$ is a damping

+The time domain equation of CPML in edge-PML and surface-PML can be derived directly following the above way used to get the

+\\
+\section{Time scheme for the convolution terms}
+The last step is to find a recursive way of computing all the convolutions.
+Equations for first-order convolution
+performed using the first-order-accurate recursive approach of \cite{LuHu92}
+(but they are unstable in practice):
+\begin{equation}
+\partial_{\tilde{x}} = \frac{1}{\kappa_x} \partial_ x + \psi_x
+\label{memory_variable_replace}
+\end{equation}
+%
+with
+\begin{equation}
+\psi_x^n = b_x \psi_x^{n - 1} + a_x \left(\partial_ x\right)^{n - \frac{1}{2}} \, .
+\label{time_evolution_psi}
+\end{equation}
+%
+Equations for second-order convolution:
+%
+To get a stable time scheme we thus use the second-order-accurate recursive approach developed recently in in Wang and Texeira 2006,
+which is that for a mathematical convolution
+$$f(t) = a {\rm e}^{-bt} H(t) * u(t) = a \psi_(t)$$
+from Wang and Texeira 2006 we know that we can compute the discrete form using
+\begin{equation}
+\psi^n = {\rm e}^{-b \Delta t} \psi^{n-1} + (\frac{1}{b} (1 - {\rm e}^{-b \Delta t /2})) u^n
++ (\frac{1}{b} (1 - {\rm e}^{-b \Delta t /2 }) {\rm e}^{-b \Delta t /2} \ ) u^{n-1}
+\end{equation}
+%
+It can also used to compute mathematical convolutions as following
+$$g(t) = [a {\rm e}^{-bt} t H(t)] * u(t)$$
+which gives
+$$g(t) = \int_{-\infty}^{t} a {\rm e}^{-b (t-\tau)} (t-\tau) H(t-\tau) u(\tau) d \tau$$
+according to linearity of convolution we have
+$$g(t) = at\int_{-\infty}^{t}  {\rm e}^{-b (t-\tau)} H(t-\tau) u(\tau) d \tau - a\int_{-\infty}^{t}  {\rm e}^{-b (t-\tau)} H(t-\tau) \tau u(\tau) d \tau $$
+or
+$$g(t) = at [  {\rm e}^{-bt} H(t) * u(t)] - a [ {\rm e}^{-bt} H(t) * (t u(t))] $$
+Then the same discrete scheme (19) can be used to compute the first and second  square brackets term on the right hand.
+%
+Also we can used to compute mathematical convolutions as following
+$$g(t) = [a {\rm e}^{-bt} t^2 H(t)] * u(t)$$
+which gives
+$$g(t) = \int_{-\infty}^{t} a {\rm e}^{-b (t-\tau)} (t-\tau)^2 H(t-\tau) u(\tau) d \tau$$
+according to linearity of convolution we have
+$$g(t) = at^2\int_{-\infty}^{t}  {\rm e}^{-b (t-\tau)}  H(t-\tau) u(\tau) d \tau -
+2at\int_{-\infty}^{t}  {\rm e}^{-b (t-\tau)}  \tau H(t-\tau) u(\tau) d \tau+
+\int_{-\infty}^{t} a {\rm e}^{-b (t-\tau)} \tau^2 H(t-\tau) u(\tau) d \tau$$
+or
+$$g(t) = at^2[{\rm e}^{-bt} H(t) * u(t)] -
+2at[{\rm e}^{-bt} H(t) * (t u(t))]+
+[ {\rm e}^{-bt} H(t) * (t^2 u(t))]$$
+Then the same discrete scheme (19) can be used to compute the first, second and third square brackets term on the right hand.
