Abstract : Computer aided design (CAD) is routinely employed in the structural and mechanical design of ships and aircraft. With relatively minor modifications, the same geometry databases can be used by computational electromagnetics (EM) codes for antenna and radar cross section analysis. A step-by-step procedure is described to obtain triangular facet models derived from CAD data files. The facet models can be used by EM codes such as PATCH and NEC. Computer code listings of translation software and instructions for use are included.
