Calculation of losses on printed circuit board by finite element method

Abstract

The attenuation constant due to conduction and dielectric losses are calculated by using a finite-element approach. The approach takes into account the skin effect and proximity effect between tracks on a printed circuit board environment and is used to predict the per-unit-length parameters needed for simulation. Results show that for typical high-speed applications the dielectric losses are comparable to the conductive losses, for frequencies close to 1 GHz.<>
