General Electromagnetic Model for the Analysis of Complex Systems (GEMACS) computer code documentation (version 3), volume 3, part 3
Abstract
GEMACS, the General Electromagnetic Model for the Analysis of Complex Systems solves electromagnetic radiation and scattering problem. The Method of Moments (MOM) and Geometrical Theory of Diffraction (GTD) are used. MOM is formalized with the Electric Field Integral Equation (EFIE) for wires and the Magnetic Field Integral Equation (MFIE) for patches. The code employ both full matrix decomposition and Banded Matrix Iteration (BMI) solution techniques. The MOM, GTD and hybrid MOM/GTD techniques in the code are used to solve electrically small object problems, electrically large object problems and combination sized object problems. The computer code documentation is given.
