Abstract

Anisotropic layers with real permittivity and permeability tensors are used to enclose the computational domain for vectorial modal analysis of dielectric waveguides through the finite element method. The approach does not require any iterative procedure. It is computationally efficient and reliable, it can directly calculate many modes at the same time, and it is very accurate in providing both the vectorial field distribution and the propagation constant. Analysis of performances is provided for different dielectric waveguides by varying the constituent parameters of the layers.
