Research Abstract	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.
