A Second-Kind Fredholm Integral-Equation Approach for Simple Low- and High-Frequency Solutions of the Perfectly-Conducting Circular Disk

The electromagnetic interaction of a vertical magnetic dipole axially symmetric with an infinitesimally thin perfectly conducting circular disk is studied and solved by transforming the original dual integral-equation system describing the problem into two forms of the single second-kind Fredholm integral equation. In this way, simple low- and high-frequency asymptotic solutions are easily derived. Numerical results are provided to validate the proposed solutions.
