Diffraction Waves on a Spherical Resonator Segment

The application and the generalization of the regularization tasks of the diffraction of electromagnetic waves on a sphere with the circular aperture are proposed. We examine the diffraction of the plane wave, on sphere. We solve auxiliary integral equations of Abel´s type and select main parts of functional equations by introducing the small parameters. As a result we obtain disconnected linear algebraic equations of second kind of Fredholm´s type. New possibilities of improvement of computational algorithms and different characteristics of spherical antennas (radiation pattern, radiation power, field profiles of different resonant modes, radar cross section, wideband signals) are discussed
