FINITE-DIFFERENCE TIME-DOMAIN MODELING OF HIGH-SPEED ELECTRONIC PACKAGES

This paper examines the modeling of complex structures having fine fea tures such as electronic packages and microstrip antennas. The numeric al analysis is carried out using the finite difference time domain (FD TD) method. One of the fundamental problems associated with analyzing this class of structures is that accurate modeling of their fine featu res typically requires a large mesh and an exorbitant amount of comput ational time. The basics of FDTD and its application to electronic pac kage structures are discussed.
