Abstract :
An attenuator structure for FWGTWT was designed and optimized for a good match to the folded waveguide circuit, SII<-20 dB from 90 GHz to 98 GHz for single port system. The equivalent relationship between dielectric loss and conductivity loss was described and discussed in this paper, in order to load the attenuators in beam/wave interaction simulation using MAFIA.
