Complex-source-point beam scattering by a thin high-contrast dielectric disk

In this paper, we consider the scattering of a complex-source-point beam by a thin high-contrast dielectric disk. To find the solution of the problem, we use analytical-numerical method which is based on the generalized boundary conditions, dual integral equations, and the method of analytical regularization. We present the normalized radiated and absorbed powers as functions of the electrical radius of the disk and far field radiation patterns of the total field at resonance points.
