Resonance Characteristics in Oversized Slow-Wave Structure of a Multiwave Cherenkov Generator with Diffraction Reflectors in Sub-THz Frequency Range

Numerical investigations of electrodynamic characteristics of the oversized two-section slow-wave structures with the diffraction reflectors were carried out. Dispersion characteristics of the symmetric TM modes, the quality factors, transmitted power of the coupled wave resonances and examples of the longitudinal resonances in two-section slow-wave structures with diffraction reflector are presented. We found out the most effective topology of the electric fields for the oversized electrodynamic structures of multiwave Cherenkov generator in sub-THz frequency range from the point of views of power increasing, and high Q-factor values.
