  • Abstract
    Theoretical analysis of a broad bandwidth confocal waveguide for W-Band gyro-TWT is presented. This waveguide effectively suppresses the undesired modes, and therefore has extremely low mode density. Stable single-mode, broad bandwidth operation is achieved in the HE0,6 mode. The confocal waveguide could be used in high-power gyro-TWT, which can provide greater operating stability and bandwidth, especially in an overmoded waveguide structure.
