fdtd编程资料小汇总-fdtd资料集合3.rar 附件中包含了我从各个网站中找到的关于fdtd的matlab编程，多达几十个程序，分享了。[

用时域有限差分法模拟电磁波的传播，波的类型是二维TM波，运行代码可以直接出现图像，更好的理解电磁波在空间中的传播，边界是MUR边界条件。

参照葛德彪书编写的3D FDTD源文件

Fortran编写的有关二维平面TE波的FDTD仿真计算

Taflove经典FDTD程序，包含1D、2D、3D三个FDTD程序

!*********************************************************************** ! 1-D FDTD code x-direction z-polarized TEM wave propagation. 一维FDTD, x方向z轴极化的TEM波传播fortran95实现

FDTD是加拿大公司开发的基于时域有限差分法（FDTD）的微纳光子学仿真高性能多处理器麦克斯韦方程求解软件，可用于纳光子器件、工艺和材料的设计、分析和优化。
