Abstract
Three methods for elimination of spurious modes from variationally formulated Finite Element solutions of inhomogeneous and/or anisotropic dielectric waveguides are considered. The reduced integration penalty method, recently applied to EM wave problems, is compared, in terms of computational performance, to the method of transversal components by Hayata and Koshiba and to an edge element based approach. The quality of the approximations obtained and its computational characteristics testify the efficiency of the reduced integration in suppressing the main drawbacks of the penalty method, while preserving its advantages and simple implementation.
