说明：  Matlab电磁波FDTD传输程序 模拟一天线发射电磁波在不同介质中的传播。(The Finite-difference time-domain (FDTD) method belongs in the general class of grid-based differential time-domain numerical modeling methods. The time-dependent Maxwell s equations (in partial differential form) are discretized using central-difference approximations to the space and time partial derivatives. The resulting finite-difference equations are solved in either software or hardware in a leapfrog manner: the electric field vector components in a volume of space are solved at a given instant in time then the magnetic field vector components in the same spatial volume are solved at the next instant in time and the process is repeated over and over again until the desired transient or steady-state electromagnetic field behavior is fully evolved. )
