Fast computation technique of Green's function and its boundary integrals for multilayered medium structures by using Fourier series expansion and method of images

This paper presents a systematic technique to improve the convergence of the Green's function for multilayered medium structure by introducing a three-layered model into the multilayered system. The technique uses a combination of Fourier series expansion and method of images. Numerical analysis demonstrates dramatic improvements of the convergence of Green's function and its boundary integrals. (C) 1998 John Wiley & Sons, Inc.
