Finite and co-site array simulation and validation using the domain decomposition method

摘要: We have developed a state-of-the-art, user-friendly, computational electromagnetic software tool. The tool enables prediction of in situ antenna radiated patterns, active port impedance and co-site interaction effects for electrically large finite array antennas as installed on detailed platforms. Yet the techniques used maintain complete geometric detail full numerical rigor. Our solver uses hybrid technique conceived at Ohio State University (OSU) that combines element domain decomposition method (FEM-DDM) integral equation (IE) solvers. Through parallel processing computer cluster, our can solve problems with multiple arrays mounted surface platform body. validated predictions against measured data.
