Abstract:

The general electromagnetic properties and design methodology for serpentinefolded-waveguide FW amplifiers are presented. In addition, hybrid-waveguide circuit topologies,which permit greater design flexibility than the basic serpentineFW topologies, are also introduced, and their dispersion characteristics are discussed. Experimental validation of design methodology and tools is provided via test results of the recently demonstrated wideband 220-GHz serpentine amplifier, which embodies the design methodology described herein. Particular attention will be paid to the comparison between code prediction and experimental data, which are in excellent agreement.
