Numerical study of electromagnetic field scattering by an electrically resistive disk

In this paper, we study the scattering problem of a given time-harmonic electromagnetic wave by a thin electrically resistive disk. We consider a horizontal ring of electric current as a source of the incident field. To find the solution of the problem, we use analytical-numerical scheme which is based on the generalized boundary conditions, dual integral equations, and the method of analytical regularization. We present the normalized radiation patterns and total radiated power for different values of geometrical and material parameters.
