Abstract
This paper reviews recent applications of the finite-difference time-domain (FD-TD) numerical modeling approach for Maxwell's equations. FD-TD is very simple in concept and execution. However, it is remarkably robust, providing highly accurate modeling predictions for a wide variety of electromagnetic wave interaction problems. The objects modeled to date range from simple 2-D geometric shapes to extremely complex 3-D aerospace and biological systems. Rigorous analytical or experimental validations are provided for the canonical shapes, and it is shown that FD-TD predictive data for near fields and radar cross section (RCS) are in excellent agreement with the benchmark data. It is concluded that, with continuing advances in FD-TD modeling theory for target features relevant to the RCS problem, and with continuing advances in vector- and concurrent-processing supercomputer technology, it is likely that FD-TD numerical modeling will occupy an important place in RCS technology in the 1990's and beyond.
