Accurate analysis of electromagnetic scattering from cylindrical objects located near periodically corrugated surface

This paper presents a rigorous spectral-domain formulation of the two-dimensional electromagnetic scattering from a finite array of cylindrical objects located near periodically corrugated surface. The structure under consideration is an imperfectly periodic structure, in which the structural periodicity is locally broken, and the fields generally have continuous spectra in the wavenumber space. The present formulation is a spectral-domain method based on the pseudo-periodic Fourier transform, and combines the coordinate transformation method and the recursive transition-matrix algorithm.
