Far-Field Characteristics of Discrete Parabolic Reflector Made of Circular PEC Wires, Symmetrically Illuminated by Plane Waves

We consider the two-dimensional scattering of the TE- and TM-polarized plane electromagnetic waves from a discrete parabolic reflector consisting of parallel circular perfectly electrically conducting wires. Our analysis is performed in the exact formulation, fully taking into account the wave interactions between the wires. We use the method of separation of variables in the local cylindrical coordinate systems in combination with Graf's addition formulas for cylindrical functions. The scattered field patterns and total scattering cross-sections are calculated and discussed.
