Finite-element analysis of optical and microwave waveguide problems
Abstract
A vector H-field formulation is developed for electromagnetic wave propagation for a wide range of guided-wave problems. It is capable of solving microwave or optical waveguide problems with arbitrarily anisotropic materials. Infinite elements have been introduced to extend the region of explicit field representation to infinity, to consider open-type waveguides more accurately. Computed results are given for a variety of optical planar guides, image lines, and waveguides containing skew anisotropic dielectric.
