Diffraction of a Waveguide Mode at the Transverse Boundary of Magnetized Plasma

Abstract

Here we develop a general theory of mode transformation (diffraction) at the flat transverse boundary between cold magnetized electron plasma and isotropic vacuum-like medium inside a circular waveguide. The obtained results can be also directly applied to the narrow-band Cherenkov radiation generated in plasma (or in isotropic medium) by a moving charged particle bunch.
