Fast electromagnetic simulation method for large-scale quasi-periodic arrays
Quasi-periodic structures have distinctive characteristics in electromagnetic regulation and have important applications in several fields,such as antennas,radar detection,and target stealth.However,efficient and accurate electromagnetic simulation for large-scale quasi-periodic arrays has always been a crucial and difficult problem in the field of computational electromagnetics.Considering this,a parallel synthetic basis function method(p-SBFM)is proposed in this paper.Based on the geometric similarity between different units,synthetic functions in p-SBFM can be reused,which can greatly improve the efficiency.This paper is the first to verify the effectiveness of p-SBFM for analyzing multi-configuration quasi-periodic arrays.Compared to traditional electromagnetic numerical algorithms,p-SBFM can,to some extent,overcome the difficulty of balancing accuracy,efficiency,and memory consumption while analyzing large-scale quasi-periodic arrays.Thus,p-SBFM provides an effective method for applying quasi-periodic structures in terms of theoretical analysis and simulation.
