Modification of the power radiated by an electrical dipole in the presence of a thin dielectric disk

We consider the problem of electromagnetic waves emission by a horizontal electrical dipole in the presence of a thin high-contrast dielectric disk. To find the solution of the problem we use analytical-numerical scheme which is based on the 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.
