Generation of physical equivalent circuits using 3D simulations

Abstract

Physical equivalent circuits are powerful tools for EMC analysis of electronic devices, however their generation is in general cumbersome. In this paper, a procedure to generate physical equivalent circuits using 3D simulations is described. The method is based on a numerical computation of Z parameters using 3D simulations. Equivalent circuit tpoplogy and parameters are extracted from the simulated Z parameter matrix. Maxwell's equations are used in a reduced form to eliminate all effects that cannot be modelled by equivalent circuits.
