Efficient modeling of passive electronic devices using the finite-difference time domain method

This work pertains to the study of passive electronic devices with fine features, e.g., electronic packages, microstrip antennas and cavity resonators, that are analyzed using the Finite Difference Time Domain (FDTD) algorithm for solving Maxwell's equations. One of the fundamental problems associated with analyzing this class of structures is that accurate modeling of their fine features typically requires a large mesh and an exorbitant amount of computational time. In this thesis, an efficient analysis of such structures is carried out by employing several techniques in conjunction with the conventional FDTD method, which improve its computational efficiency significantly without sacrificing its accuracy. Useful techniques for handling complex structures include non-uniform spacing, subcell modeling, distributed computing and extrapolation.
