Some novel techniques for efficient analysis of large arrays and frequency selective radomes

In this paper, we have introduced three approaches to alleviating large solution times arising in the MoM. First, a new impedance matrix interpolation algorithm for planar microstrip structures has been presented to speed up the matrix generation time. Second, the characteristic basis functions method has been proposed for efficient analysis of large problems. Finally, a technique for analyzing combinations of large arrays and FSS radomes using a quasi-periodic analysis has been mentioned.
