An improved model-creation program for EM interaction analysis
Abstract
Several codes are available for computation of the interaction of electromagnetic waves with simple and complicated structures. All existing codes require as an input the geometry of the object under study. This geometry is supplied as a wire-grid, surface-patch, or cell model, depending on the simulation code. The difficulty of creating such geometric data increases with the complexity of the structure, as is the case with aircraft. To aid in this process, the DIDEC program was created, starting as a program that created wire models using a digitizing tablet. Initially, it created Numerical Electromagnetic Code input files for wire-grid structures. Since then, it has developed into an interactive program, DIDEC/DREO, for designing wire-grid, patch, and cell models of complex structures for solving electromagnetic interaction problems. The various features of the current version of DIDEC/DREO are described, with examples provided of graphic displays.
