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