Abstract
In this paper, the scattering behaviour of an electromagnetic wave by vortex flow is studied in detail by solving the first-order (in v/c) Maxwell's equation in the cylindrical coordinate system (r, Ï, z) and the general solutions are obtained. From these solutions, the differential cross-section of the vortex flow is calculated and the electromagnetic scattering characteristics of the vortex flow are discussed. The dependence of differential cross-section on the velocity profile and the radius of the vortex flow is investigated independently. Besides, by considering the dependence of scattering characteristics on the frequency of an incident wave we conclude that the vortex flow has frequency selectivity.
