Integral equation based time domain coupled EM-circuit simulation for packaged conductors and dielectrics

Abstract

A full-wave time domain integral equation formulation for the simulation of finite conductors and dielectrics, linked to linear and non-linear lumped elements, is presented. The method permits coupled rigorous simulation including accounting for EMI and non-linearities in the presence of material effects. In addition, a new quadrature scheme is incorporated for exactly computing temporal delays between every section of finite basis functions defined over triangular patches. This enables finer time step resolution for non-uniform meshes than is permissible with standard Gaussian quadrature and singularity extraction.
