Abstract

The Whitney-elements time-domain (WETD) method is a very powerful full-wave EM field solver in the time domain. The WETD method is here applied to solve a coupled problem of EM fields and circuits, which are characterized by lumped elements, distributed elements and independent sources. The method consists in the variation of the finite element functional to include circuit elements in the computational domain. By locating the terminals of the lumped elements in two nodes delimiting an edge of the FEM mesh, a simple computational procedure is obtained. The distributed elements are modeled as a series of lumped elements. The proposed full-wave method is a suitable tool to analyze electrical circuits and EM fields in complex configurations
