Control of Backscattering of H-polarized Plane Wave by aCircular Dielectric Rod with Partial Graphene Cover

Abstract

We study the problem of the scattering of the H-polarised plane wave by an infinite dielectric rod with a partial graphene cover. The mathematical model is developed based on the boundary hyper-singular integral equation which should be understood in the sense of Hadamard’s finite part. Discretization of the derived integral equation is carried out by the Nystrom-type method, which has a rigorously guaranteed convergence. With the aid of thus obtained discrete model, we plot the dependences of radar cross-section (RCS) and extinction cross-section (ECS) on the frequency, slot size and orientation angle.
