Abstract

A conjugate gradient-circular convolution (CG-CC) method of analyzing scattering from a finite surface with multiple periodicity is presented. This method may improve the accuracy and convergence of the solution by eliminating the aliasing effect introduced by the truncating procedure or periodical extension of the structure. Numerical results of the induced current distributions on 1-D and 2-D dipole arrays are presented and compared.<>
