Abstract

Two interactive-graphics input programs for high-frequency electromagnetic modelling packages are described. One (WGM) generates segmented wire-grid input for the method of moments; the other (GENIE) generates a set of flat plates for the geometrical theory of diffraction. These were written in FORTRAN-77, using the standard GKS (graphical kernel system) graphics commands in order to maximise the portability and maintainability of the software. The programs contain several features to ease the input of the physical structure of the object to be modelled and its subsequent subdivision into wire segments or GTD plates of appropriate dimensions
