| Abstract: | A two-section sine waveguide electromagnetic system is proposed for W-band high power traveling wave tube. An attenuator and an input or output structure is designed, respectively. Using particle-in-cell method, the interaction results between sheet electron beam and slow wave in this system are studied. The investigation results show that, this traveling wave tube can be applied to produce l kW peak power output ranging from 90 to 98 GHz. It, therefore, will favor the development of wideband high power millimeter-wave radiation source. |
