Abstract :
The helical groove waveguide (HGW) is a potential traveling-wave tube (TWT) slow-wave structure (SWS) for use in high power applications at millimeter frequencies. It has attracted significant attention for its large size, good heat dissipation capabilities, high precision of manufacture and assembly, robust construction and low cost. Recently, we have developed a novel HGW-SWS, the coaxial inverted helical groove structure for achieving wideband amplification in a TWT.
