Expansion of existing EM workbench for multiple computational electromagnetics codes

An "EM workbench" is described. It has a modular, code-independent architecture and a common design environment. The technique for integrating new EM codes is demonstrated with a method-of-moments code specialized for circularly symmetric feed horns, and with a new hybrid DFT-MoM (discrete Fourier transform - method of moments) code for finite-boundary planar phased arrays. The use of a common design environment for all codes takes advantage of common infrastructure and utility software, and minimizes the learning-curve penalty for using a new EM code capability.
