摘要

提出了一种结合修正表面积分法(MSI)和积分方程(IE)的近似等效原理来评估大尺寸天线罩封装阵列(AER)在发射模式下的电磁性能。采用多层快速多极算法(MLFMA)加快曲面积分速度。数值结果表明了该方法的有效性、精度和高效性。

Fast and Efficient Evaluation of Radome-Enclosed Antennas in Transmitting Mode by Modified Surface Integration
An approximate equivalent principle that combines the modified surface integration (MSI) and the integral equation (IE) is proposed to evaluate the electromagnetic performance of the antannas/arrays enclosed by radomes (AER) with large sizes in transmitting mode. The multilevel fast multipole algorithm (MLFMA) is utilized to speeding up the surface integration. Numerical results demonstrate the validity, precision and efficiency of present approach.
