Diffraction of electromagnetic waves by a partially metallized thin gyrotropic cylinder

An analysis is made of the two-dimensional problem of the diffraction of a plane wave by a homogeneously axially magnetized ferrite cylinder partially covered by a thin metallic shell. It is shown that, given a sufficiently strong magnetization of the ferrite, singular ribs exist on the cylinder surface, leading to a considerable absorption of incident-wave power. The magnetic field on the singular rib has a nonintegrable singularity which is caused by a rib-directed power flux of a sectoral unidirectional magnetostatic wave excited by a lateral field.
