In this paper, the slow-wave structure (SWS) of the “folded waveguide” -type was considered. This SWS is widely used for designing the devices in higher frequencies like millimeter and sub millimeter ranges due to its compactness, increased interaction length, reduced transit time effects, lower voltage requirements, and wide bandwidth. The calculation of its electrodynamic characteristics, ...
