Scattering Characteristics of Periodic Finite Array with Graphene Patches on Cylindrical Surface

Abstract

Plane wave scattering by a periodic finite array with graphene patches on a cylindrical surface (CPFGA) is studied. In discussed CPFGA N graphene patches are placed on a dielectric rod (DR) surface in the azimuth direction. To build a problem solution the Method of Moments (MoM) was applied in the spectral domain using Piece Wise Sinusoidal (PWS) basis functions. The cases of $\mathrm{N}=1,2,3,4$ patches are studied. The radar cross section versus frequency is studied for both E- and H-plane wave polarization. The current distributions and far fields at the resonant frequencies are calculated.
