Abstract
A Smith-Purcell FEM is studied taking into account the case when the radius of the operating waveguide is small enough and the complicated resonance oscillations caused by coupling of the operating and quasi-critical modes do not exist. Two possible variants of feedback elements, the Bragg reflectors and resonance reflectors, are theoretically discussed. Through simulations, it is shown that both methods allow realization of rather powerful and effective sources of single-mode radiation at millimeter wavelengths.
