Hybridization of Periodic Equivalence Principle Algorithm, Equivalence Principle Algorithm, and Physical Optics for Analysis of Large Finite Antenna Array with Perfect Electrically Conducting Object

Abstract

In the solution of a radiation problem on a large-scale antenna array with a large perfect electrically conducting object, the equivalence principle algorithm hybridized with physical optics has been used to accelerate the calculation. However, the efficiency of this hybridization will be low if the number of elements in the antenna array is large. This article proposes a novel method to speed up the equivalence principle algorithm hybridized with physical optics by introducing the periodic equivalence principle algorithm. The calculation of the couplings among the elements will be simplified, and the elapsed time will decrease. At the same time, the total memory required will be saved. ARTICLE HISTORY
