Full-vectorial analysis of optical waveguides by the mapped Galerkin method based on H-field

Mapped Galerkin´s method is employed to solve the full-vectorial wave equations in terms of transverse magnetic fields, for optical waveguides. By transforming the whole x-y space into a unit square and using two-dimensional Fourier series expansion, the modal distributions and propagation constants for the buried rectangular are obtained in the absence of boundary truncation. Solutions are good agreed with those published earlier.
