Abstract

The aim of this paper is to study some problems arising in simulating structures on printed circuit boards. Hexahedral edge finite elements of second order using different potential formulations have been employed. Some simplifications are proposed to reduce the computational effort. The input impedance of a micro strip on a test board is computed and compared with measurement data. Some numerical issues are investigated. A semi-analytical method to compute the losses in the microstrip and in the board is presented and results are shown
