Title: Embedded monofilament UV-LIGA techniques for microfabrication of beam tunnels in a 220 GHz wideband serpentine waveguide amplifier
Abstract: A 50 watt, wideband serpentine amplifier is under development to demonstrate a novel beam tunnel fabrication technique capable of forming arbitrarily long beam tunnels of very small diameter using a single Ultraviolet Lithography (UV-LIGA) exposure step.
