Abstract :
Numerical solution for coupling into and scattering from uniform array of patches or apertures conformed to a circular cylinder is presented. The work outlines some scattering features of cylindrical structures as a frequency selective surface (FSS). The numerical technique of analysis is the conjugate gradient (CG) iterative scheme in conjunction with the fast Fourier transform (FFT)
