Description: 各向同性空隙介质中波的传播的解析形式，应用下文的方法：
Dai, N., Vafidis, A. & Kanasewich, E.R., 1995. Wave propagation in heterogeneous, porous media: A velocity-stress, finite-difference method, Geophysics, 60, 327-340.
更加详细的介绍见英文描述，该代码对于做波场模拟的同学有很好的参考价值。-MATLAB Script for obtaning the analytical solution for wave propagation in a homogenous poroelastic medium, based on the solution described in the paper by Dai et al. (1995).
The source used is a point explosion with time component Ricker or gaussian first derivative. The solution is computed in the frequency domain. Only non-viscous fluids are considered. The resulting seismograms are the radial components of the solid and liquid particle velocities.

Description: This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells.
To illustrate the algorithm, a 6-cm-diameter metal cylindrical scatterer in free space is modeled. The source excitation is a Gaussian pulse with a carrier frequency of 5 GHz.
The grid resolution (dx = 3 mm) was chosen to provide 20 samples.
