Abstract

The time domain adaptive integral method is used to accelerate the process of solving a combined field integral equation (CFIE). To evaluate the magnetic field contribution to the CFIE, the vector potential is computed on an auxiliary mesh and spatial finite differences are used to evaluate its curl. Simulation results demonstrate the accuracy and efficiency of this approach.
