Scattering by a magnetized plasma-coated topological insulator cylinder

摘要

In the present paper, the scattering characteristics of a magnetized plasma-coated topological insulator cylinder are formulated and analysed graphically. Field equations at each interface are expanded in terms of cylindrical wave vector functions by imposing extended classical wave-scattering theory. By applying the boundary conditions, scattering matrices are obtained in terms of scattered and transmitted coefficients. The obtained results are also compared with published results to display the accuracy of the present formulation under some special conditions. Changes in the bistatic echo widths of the topological insulator cylinder are also recorded by varying the anisotropic plasma parameters (i.e., the applied magnetic field, plasma density and effective collisional frequency).
