Electromagnetic simulations in frequency and time domain using adaptive integral method

Abstract

The subject of this thesis is to investigate methods to improve the performance of the adaptive integral method (AIM) for effective large scale simulations in both the frequency and the time domain. This is achieved by reducing the storage requirements, decreasing the amount of computational loads and implementing effective parallelization strategies. The methods presented in this thesis include an efficient novel magnetic field integral equation (MFIE) testing scheme for AIM, the interlaced fast Fourier transform (FFT) method for solving general scattering problems, a parallelized fast partial matrix solver for the simulation of very large scale microstrip circuits and the improved block aggregate matrix vector multiply for time domain adaptive integral equation method (TDAIM).
