Analysis of Conformal Periodic Arrays Using Cylindrically Periodic Stratified Media Green’s Functions and PWS-MoM

A cylindrically periodic stratified media Green’s Functions (CPSMGFs) method is proposed to analyze conformal arrays through one array unit. The CPSMGFs are developed on electric dyadic closed-form Green’s Functions (CFGFs) and modified two-dimensional (2D) periodic boundary conditions. A modification is made to the method of moments to fit the piecewise sinusoidal basis function. The convergence of this method is evaluated. Compared with one-dimensional (1D) periodic boundary method in FEKO, the accuracy of this method is verified, and the analysis efficiency of conformal arrays is improved by over two orders of magnitude.
