Bulk Resonances of Symmetric Hybrid Waves in an Overmode Biperiodic Slow-Wave Structure

Resumo

The electrodynamic characteristics of a biperiodic slow-wave waveguide have been investigated numerically. Conditions have been found for the existence of an anomalous dispersion of the TM₀₁ mode at frequencies approaching the π-type oscillation frequencies. The slow TM₀₁ modes propagating in a periodic and in a biperiodic waveguide have been compared in field structure. A method for calculating the eigenfields (resonances) in a biperiodic waveguide section of finite length is proposed.
