Summary: | The paper puts forward a novel dual beam folded waveguide (FW) slow wave structure (SWS), which is loaded by photonic crystals. In this novel structure, the two electron beams pass through the small gaps between the photonic crystal structures and the folded waveguide. According to Particle-in-cell simulations by the CST Particle Studio, the designed traveling wave tube (TWT) can generate a peak power of 210W at 220GHz, corresponding to the maximum gain and efficiency of 16.3dB and 5%, respectively. |
