Abstract :
Our research concentrates on the numerical study of electromagnetic scattering or radiation from doubly periodic infinite structures by the method of moments (MoM), which find applications in phased arrays and metamaterials. The range of inter-element phase shifts of our interest extends from 0 to 2pi if we use the array scanning method (ASM) in post processing to compute the scattered or radiated fields in case of non-periodic excitations.
