Here we imply a zero- thickness perfectly electrically conducting (PEC) disk, and also thin electrically resistive (ER) and dielectric disks whose thickness is much smaller than the disk radius and the free space wavelength, and also much smaller than the skin-layer depth in the ER disk case. The method used for the modeling is based on the integral equation (IE) technique and analytical regularization. Starting with Maxwell's equations, boundary conditions and the radiation condition at infinity we obtain a set of coupled dual IEs (DIEs) for the unknowns and then reduce this set of equations to the coupled IEs of the Fredholm second kind. To verify our results we calculate the far field characteristics in the case of the PEC disk with the incident field being the field of horizontal electrical dipole located on the disk axis.EnglishAnalytical regularizationDiffractionDiskDielectric disksElectrical dipolesFar fieldFredholmFree spaceFree-space wavelengthsIncident fieldsMethod of analytical regularizationPerfectly electrically conducting disksRadiation conditionThin diskAntennasDielectric materialsDisks (machine components)Electromagnetic wave diffractionElectromagnetic wave scatteringElectromagnetic wavesMaxwell equationsSet theoryDisks (structural components)Conference Paper10.1049/ic.2007.1181
