Rare electromagnetics smith chart program (QuickSmith). Very good and easy to use smith chart program. User can do impedance matching using components easily. It is a 16-bit application, so it runs only on WinXP or below.

Computational Electromagnetics

代码适用于Matlab模拟的电磁学时域有限差分法（FDTD）。代码开发建立在Matlab程序语言基础上，因为Matlab程序易于使用、实用性强，并且大多电子工程师对Matlab 语言较为熟悉。(The code is applicable to the electromagnetics time domain finite difference method (FDTD) for Matlab simulation. Code development is based on Matlab pr
