SLOW-WAVE STRUCTURE FOR MICROWAVE ELECTRONIC DEVICES Russian patent published in 1995 - IPC

FIELD: electronic instrumentation engineering. SUBSTANCE: each resonator of slow-wave structure has external and internal conductors of coaxial waveguide which is divided into individual resonators by lateral diaphragms with azimuthal coupling slots and holes to let pass electron current. Metal disc with holes for passing of electron current is inserted coaxially to longitudinal axis of system, is fixed on surface of one of conductors of coaxial waveguide and forms ring clearance together with the other conductor. EFFECT: increased resistance of working spatial harmonic, expanded bandwidth of slow-wave structure. 5 dwg
