Substitutive divergent bases for FEM modelling of field singularities near a wedge

A finite-element implementation for the analysis of propagation constants and fields in a guiding structure is presented in this paper. The solution explicitly takes into account the field divergence on the edges of the internal wedges by exploiting substitutive divergent bases. © 2005 Wiley Periodicals, Inc.
