Biperiodicity in Coupled-Cavity Traveling-Wave Tubes.

Abstract

This study concerns analysis of wave propagation in coupled-cavity traveling-wave tube (CCTWT) interaction structures having the feature of biperiodicity: The alternating between two different geometries of consecutive resonators or coupling interfaces or both. Brillouin diagrams are computed and discussed for a number of existing and proposed biperiodic circuit structures. A better understanding of propagation in biperiodic structures is valuable because: (1) A biperiodic structure can provide a unique w-B curve with features benefiting hot bandwidth and stability. (2) A nonbioperiodic structure can become biperiodic through fabrication deficiencies with consequences detrimental to tube performance, and (3) Some nonbioperiodic CCTWT structures are biperiodic with respect to spurious higher-order modes resulting in interference detrimental to tube operation.
