Electromagnetic response of multiple conducting cylinders coated with chiral material

An analytical solution is derived for the scattering of an electromagnetic plane wave from parallel multiple perfect electric conducting (PEC) circular cylinders coated with chiral material. The PEC cylinders and the coating layer are infinite along the axes of cylinders. Parallel polarization has been considered for the analysis. Comparison is carried out between the results for PEC cylinders coated with chiral material and coated with ordinary dielectric material. The numerical results are compared with the published literature and are in good agreement. It has been observed that forward and backward scattered fields of parallel chiral coated PEC cylinders depend on the thickness of chiral coating material, and can be controlled with suitable selection of parameters.
