一个真正意义上的C++（不是C语言）编写的FDTD二维TM波算法程序，是老师给的作业，给大家共享。-A true sense of the C++ (not C language), prepared by two-dimensional TM wave FDTD algorithm procedures, teachers are given homework, give everyone shared.

c语言编写的FDTD算法代码，可直接在linux等平台运行makefile文件，windows可以稍作修改即可使用(C language FDTD algorithm code, can be directly in the Linux and other platforms running makefile files, windows can be modified slightly can be used)
