Abstract :
The TSAR electromagnetic modeling system consists of a family of related codes that have been designed to work together to provide users with a practical way to set up, run, and interpret the results from complex 3-D finite-difference time-domain (FDTD) electromagnetic simulations. TSAR was originally developed to analyze high-power microwave and EMP coupling problems. However, the general-purpose nature of the tools has made it possible to use the codes to solve a broader class of electromagnetic applications and has motivated the addition of features. In particular, a family of near-to-far field transformation routines has been added to the codes, enabling TSAR to be used for radar-cross section (RCS) and antenna analysis problems.<>
