A wide-use computer code is developed for the numerical solution of electromagnetic scattering and diffraction problems. The method of numerical analysis is Yasuura's mode-matching method, which is known widely as a rigorous modal expansion approach with proof of convergence. In order that an engineer without deep knowledge in computational electromagnetics can use the computer code, it is equipped with a GUI environment : the engineer is able to formulate a problem following the directions on his monitor ; and he obtains the result of numerical analysis either in graphics or in mumerical files. This works as a good educational tool for computational electromagnetics. Further, because the code is written in FORTRAN and VisualBasic, one can easily modify a part of the program to have an effective computer code for his particular interest.

编制了一个广泛应用的电磁散射和绕射问题的数值计算程序。数值分析的方法是Yasuura的模式匹配方法，这是众所周知的严格的模式扩展方法的收敛性证明。为了使没有深厚的计算电磁学知识的工程师可以使用计算机代码，它配备了一个GUI环境：工程师能够按照显示器上的指示制定问题;他获得了图形或数字文件中的数值分析结果。这是计算电磁学的一个很好的教育工具。此外，由于代码是用FORTRAN和VisualBasic编写的，因此可以很容易地修改程序的一部分，以便为他的特定兴趣提供有效的计算机代码。
