The goal of this proposal is to apply new MEMS fabrication techniques to demonstrate and evaluate the design of a new THz klystron amplifier. A possible MEMS-based fabrication process to realize the THz klystron amplifier will be described.
Design and analysis of a slow-wave structure (SWS) potentially applicable to high power traveling-wave tube (TWT) amplifiers at millimeter-wave frequencies are presented. The circuit characteristics, including the dispersion relation, are predicted. Hot test particle-in-cell (PIC) simulation results will be described employing VORPAL that is based on the conformal finite difference time domain (CFDTD)...

The design of slow wave structures for microfabricated millimeter-wave traveling wave tube amplifier is described. Results on critical design parameters, dispersion relations, and output power is also presented. Full three dimensional electromagnetic simulation is performed for cold circuit analysis. And the device performance is evaluated using small and large signal simulations codes.
