Abstract

A novel finite-gap lumped-port model is presented to improve the accuracy of the volume surface integral equation (VSIE) solver for electromagnetic (EM) radiation from composite metallic-dielectric structures. This port model is implemented by modifying the traditional method of moments (MoM) solution to use a novel divergence-conforming testing function at the gap as well as half-basis functions connected across the gap, where a small gap region in the domain of analysis is linked to the lumped-circuit voltage/current source. Then, a hybrid multilevel fast multipole algorithm with multilevel accelerated Cartesian expansion algorithm (MLFMA-MLACEA) is adopted to enhance the capability of this VSIE-based finite-gap lumped-port model for electrically large and multi-scale EM radiation problems. Numerical results are provided to demonstrate the accuracy and efficiency of this VSIE method.
