Abstract
An efficient and accurate vectorial finite element formulation is pres ented for the analysis of dielectric waveguides with arbitrary cross-s ections, nonlinear behaviors, and anisotropic materials. Remarkable im provements in solution precision and computational effort have been ob tained by evaluating new coefficients used in the matrix assembling pr ocedure of the method. The influence of the mesh division is discussed and comparison with a scalar finite element approach is reported.
