Diffraction of Circularly Polarized Waves at Semitransparent cylinders with Anisotropic Mixed Conductivity

摘要

Scattering of circularly polarized plane waves at a semitransparent cylinder with mixed conductiv- ity along the helical lines is investigated. Low-frequency resonances at the cylinder eigenfrequencies are stud- ied. Explicit expressions for the resonance frequencies are obtained. The scattering characteristics are calcu- lated as functions of the frequency and incidence angle of a plane wave.
