Summary:
The present paper formulates the electromagnetic scattering by a structure consisting of a periodic array of circular cylinder and another circular cylinder located in front of the array. Periodicity of the structure is locally collapsed and the standard formulations based on Floquet’s theorem cannot be applied. In this paper, pseudo-periodic Fourier transform is formally introduced to analyze the problem. This transform makes the field components pseudo-periodic and they are then expressed in the Rayleigh expansion outside the cylinders. The recursive transition-matrix algorithm with the help of Yasumoto et al’s formula for the lattice sums is used to calculate the scattering by the periodic cylinder array.
