Abstract
This article, based upon invited papers at the XXII URSI General Assembly (Tel Avic, August 1987) and the URSI National Radio Science Meeting (Boulder, January 1988), reviews recent applications of the finite-diffrerence time-domain (FD-TD) method for numerical modeling of electromagnetic waves scattering and interaction problems. One of the goals of this article is to demonstrate that recent advances in FD-TD modeling concepts and software implementation, combined with advances in computer technology, have expanded the scope, accuracy, and speed of FD-TD choice for structures that cannot be easily treated by conventional integral equation and asymptotic approaches. As a class, such structure are electrically large and have complex shapes, material compositions, apertures, and interior cavitiesKeywords
