In an attempt to quantify the performance of pulsed antenna systems, we have combined TSAR, a three-dimensional finite difference time domain electromagnetics modeling code, and MAXWELL3, the finite element counterpart of TSAR, with a general purpose near-to-far field transform post-processor FAR. TSAR and MAXWELL3 predict for a particular geometry the fields over a generally specified surface and the post-processor FAR then generates from these near-fields, the far-field time histories and/or the field patterns at particular frequencies via a Fourier transform. The application of these algorithms to modeling the overall antenna system performance when breakdown regions occur near the antenna is being studied and will be discussed. 3 refs., 4 figs.
