Abstract

A truncated, nonuniform, finite array of strips does not have a closed form solution. Using translational symmetry, a recursive algorithm that calculates the scattering solution with N log2N computational complexity is described. First, the algorithm is validated with the method of moments for both the TM to-z and TE-to-z polarizations. Then the scattering solution from a large strip is calculated for both TE and TM polarizations. The current distribution for the TE polarization shows small-length-scale oscillations not present in the TM polarization.
