Abstract

Wave scattering of a truncated, nonuniform, finite array of strips (with or without dielectric supporter) is investigated using a recursive algorithm that calculates the scattering solution with N log/sup 2/ N computational complexity. The algorithm is validated with the method of moments. The scattering solutions from large strips and strip arrays are calculated for both E/sub z/ and H/sub z/ polarizations. The current distribution for the H/sub z/ polarization shows small-length-scale oscillations not present in the E/sub z/ polarization.<>
