Estimation of interfrence between antennas on large platforms using physics-based truncation model and multi-level fast multipole method

Abstract

This paper proposes an efficient method to estimate interference between antennas on large platforms. Due to the large size of the platform, calculation of interference between antennas on large platforms is time consuming even using a fast integral equation method like the multi-level fast multi-pole method (MLFMM). After analyzing coupling mechanisms, it is found that interference between antennas is mainly affected by a small portion of the large platform. Based on this observation, the large platform is truncated to save computational effort. The truncation model is then analyzed by MLFMM. Simulation results are presented to illustrate the effectiveness of the proposed method.
