Abstract

A preliminary study regarding the potential of a time-domain finite-volume method to solve radiation problems has been carried out. The results of this preliminary study are very encouraging and reveal a great potential in dealing with various kinds of radiating structures. This potential in the area of printed antennas is particularly important because printed antennas often comprise multilayers of dielectric materials with nonplanar profile. Another area of application of the proposed method is computation of antenna transients and radiation due to nonsinusoidal excitations. Some sample results are presented, namely radiation contours and radiation patterns for an open-ended parallel-plate waveguide, a two-dimensional horn, and a binomial array of parallel-plate waveguides.<>
