Abstract :
The fast Fourier transform is applied to accelerate the computation of the behavior of elements in infinite periodic arrays. Results of an implementation of this technique for general 3-D elements in an arbitrary planar lattice are presented. This technique was incorporated into the Finite Element Radiation Model (FERM) method of moments code.<>
