Matlab code FDTD 2D ( dennis sullivan book )

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)
