Study of Novel Helical Slow-Wave Circuits for Millimeter Wave TWTs

摘要

Using simulation code MAFIA, three novel helical slow-wave structures (HSWSs) with diamond as support material are studied and then are suggested to improve the performance of a Ka-band millimeter wave TWT. The nonlinear analysis is carried through using BWI module in TWTCAD Integral Framework and the results have been found to be consistent with the expectation.
