Simulation of the mutual couplings among multiple antennas on large platform using multi-region multi-solver domain decomposition

Modern aircrafts are usually equipped with multiple antennas serving for different usages, including radar, communication, etc. Many of them have highly contrasting power levels and overlapping frequency bands. The mutual couplings among antennas may cause severe electromagnetic compatibility (EMC) problem, which prevents the multiple antennas from working simultaneously. This paper proposes a multi-region multi-solver domain decomposition method (MS-DDM) to simulate the EMC problem on electrically large platform. It has been successfully applied to analyze the mutual coupling between complex antennas mounted on a real F-16 aricraft at 2GHz frequency.
