Abstract :
Method of moments applied to surface integral equations combined with higher-order basis functions enables full-wave analysis in frequency domain of complex and relatively large structures. The electrical size of solvable problems can be further extended using different techniques: symmetry of the problem, "smart reduction" of expansion orders, physical optics driven method of moments, iterative methods, multilevel fast multipole algorithm, out-of-core solver, and parallelization at CPU/GPU. Results are presented for: (1) monostatic RCS of cube of side 50λ (100λ), (2) beam steering of array of 40 by 40 microstrip patch antennas at 9.2 GHz, and (3) beam steering of 4 by 4 patch antennas at 2 GHz (5 GHz), placed on a 19-m long helicopter.
