Abstract :
The extended interaction oscillator (EIO) is regarded as a novel type of high power terahertz (THz) source, which has promising applications prospects in military radar, medical imaging and wireless communications, etc. For being satisfied with the widely applications, a THz EIO operation at G-band is designed and studied with three-dimensional particle-in-cell simulation at IECAS. To improve the output power of EIO, a novel type of beam-wave interaction system composed of two-section folded waveguide is presented in this paper. The parameters including periods, drift length are designed with the equivalent circuit model and 3D PIC. According to the optimum parameters, the two-section folded waveguide with UV-LIGA and high speed milling, the S-parameters are tested. The results show that the output power can be improved by a factor of 2 and the transmission attenuation is about -10dB.
