Robust numerical approximation of 2.5‐dimensional electromagnetic problems by using finite elements

Abstract

When a numerical method is used to analyze or design an electromagnetic structure, as the finite element method, the introduction of the behavior of some component of the electromagnetic field (when this is known) allows to project the physical problem onto a two-dimensional mesh, multiplying the capacity of the method to make efficient computer aided design of complex devices as they are demanded nowadays. Though this is an old issue, which has been focused one or two decades ago, the arrival of higher-order function basis and powerful tools of meshing and post processing makes interesting to review this important field within the computational electromagnetic area.
