Investigations of folded waveguide TWT oscillators for THz radiation

In this paper we are investigating folded waveguide traveling wave tubes (FWGTWT). These FWGTWTs combine the power density and high frequency advantages of vacuum microelectronics with the powerful microfabrication methods of MEMS and solid state electronics. Experimental, theoretical and computer simulation investigations of a FWGTWT oscillator have been performed, including microfabrication tests of a variety of methods.
