Analytical Solution of the Zero-Thickness Perfectly-Conducting Circular Disk in the Presence of an Axisymmetric Magnetic Dipole: a Second-Kind Fredholm Integral-Equation Approach

The problem of radiation of a magnetic dipole axially symmetric with an infinitesimally thin perfectly conducting circular disk is solved in an exact closed form. This is done by transforming the original dual integral equation system describing the problem into a single second-kind Fredholm integral equation and searching for the solution as a power series. Both low- and high-frequency asymptotic limits are also discussed from which simple approximate solutions are readily derived. Numerical results are provided to validate the proposed formulation.
