| Abstract: | In this paper we present an iterated moment method (JMM) for evaluation of dispersion relations of dielectric waeeguides with arbitrary cross-section. Numerical results are given for fibers of various shapes. These arc circles, ellipses, equi-lateral triangles, chipped-circles and egg-shaped cross-sections. The results agree well with exact computer-aided numerical results by finite element method and pointmatching method, The present method is simple and saves computation time. |
