Análisis de guías parcialmente rellenas de dieléctrico mediante el método de los elementos finitos

Abstract

The finite element's method is aplied to the study of inhomogenous waveguides of arbitrary cross-section. The fields in the guide are - expanded in a series of bidimensional functions, obtaining a variational expression that is minimized in each subdomain. The eingenvectors of the resulting matrix are related with the waveguide modes and the eingenvalues with the propagation constants.
