On the theory of a circular waveguide with anisotropic impedance surface for gyro-devices: Beam-wave interaction

In [1], the “cold” (beam-absent) theory of a finite-length circular waveguide with anisotropic surface impedance was presented. The purpose of the present paper is to derive the self-consistent system of equations describing stationary regime of the beam-wave interaction in the gyro-device with an interaction structure in the form of such waveguide. Similar equations valid for a perfectly conducting waveguide are well-known [2–5] and in active use.
