The study presents a universal approach to solving a boundary value problem for waveguide of arbitrary crosssection with longitudinally magnetized plasma filling. The approach utilizes representation of longitudinal fields ...

Electromagnetic analysis of a cylindrical gyrotron cavity with longitudinal wall corrugations is performed on the basis of the approximate surface impedance model (SIM) and the full-wave spatial harmonic method (SHM). ...

It is shown that a formation of hybrid modes (mode hybridization) in a gyrotron cavity occurs as their frequencies approach coincident points induced by background plasma. Such process, which is accompanied by a drastic ...
