Analytical regularization of dual integral equations in the electromagnetic scattering by a resistive disk

The interest to the printed antennas including circular antennas is kept high since long ago. It is explained by several facts such as their low profile, low cost, light weight, etc. Many methods commonly applied in electromagnetic theory have been used in their analysis, starting with empirical methods and finishing with method of moments (MoM) and finite difference time domain methods (FDTD). However, use of these methods leads to difficulties such as prohibitively large matrices and impossibility of estimation of the error of calculation. Using the method of integral equations (IEs) with analytical regularization it is possible to escape these difficulties. It consists in splitting integral operators in two parts and inverting the singular parts. This leads to the IEs of Fredholm second kind.
