Output Performances by Particle-In-Cell Simulations for 0.108THz Folded Waveguide Slow-wave Structures

In this paper, we modelled a sub-Terahertz at the frequency of 0.108THz folded waveguide traveling-tube (FWTWT) by utilizing a 3-D particle-in-cell (PIC) in CST STUDIO SUITE., and we investigated the beam and electromagnetic field of 108GHz slow-wave structures (SWS). The process of the interaction...

Summary:In this paper, we modelled a sub-Terahertz at the frequency of 0.108THz folded waveguide traveling-tube (FWTWT) by utilizing a 3-D particle-in-cell (PIC) in CST STUDIO SUITE., and we investigated the beam and electromagnetic field of 108GHz slow-wave structures (SWS). The process of the interaction for SWS are presented, including working voltage, the structural parameters, working frequency. The radiation power and gain of the SWS at 108GHz is 42.32W and 26.26dB. The output of the SWS changes only 1.2dB across the 7Ghz bandwidth ranging from 103Ghz to 110GHz., which is useful in many fields, such as communications, electronic countermeasures, radar.
