THE INTEGRAL EQUATION METHOD FOR SOLVING PROBLEMS OF DISCONTINUOUS DIELECTRIC STRUCTURE

摘要

From the mode-marching method,by doing some transforms and derivations,the scatteringand propagation integral equations for solving the problems of discontinuous dielectric structure are ob-tained.The necessary and sufficient condition for the existence of solution of propagating equations is giv-en.It is really the dispersion equation of the dielectric structure.As an example,a succinct solution ofone-step discontinuous dielectric structure is derived.
