中文摘要:提出一种改进的曲折槽波导—曲折双脊槽波导提高太赫兹行波管的功率和带宽.针对这种新型慢波结构设计了一种新的传输波导作为输入输出能量耦合器.从高频特性仿真结果可以发现曲折双脊槽波导可以提高耦合阻抗并扩展带宽.此外, 粒子仿真结果表明当电子注加载27.4kV电压和0.25A电流时, 新型曲折双脊槽波导行波管在中心频率340GHz处输出功率能达到65.8W同时对应增益27.21dB.因此, 曲折双脊槽波导行波管可以用作宽带和高功率太赫兹辐射源.

High power wideband terahertz traveling wave tube based on folded double ridge groove waveguide
Abstract:A modified folded groove waveguide called folded double ridge groove waveguide (FDRGW) is put forward for developing broadband high-power terahertz (THz) travelling-wave tube (TWT) .A newtransmission waveguide which is appropriate for this newkind of SWS as input and output energy coupler is proposed.It can be found from the high frequency characteristic simulation results that the folded double ridge waveguide SWS can increase the average interaction impedance and extend its operating bandwidth.In addition, the particle-in-cell (PIC) simulation results reveal that with the beam voltage of 27.4 kV and the beam current of 0.25 A, the average output power of the newfolded double ridge groove waveguide TWT can reach 65.8 W and the corresponding gain is 27.21 dB at the center frequency 340 GHz.Therefore, the folded double ridge groove waveguide TWT could be used as wide-band and high-power terahertz radiation source.
