Abstract: A novel slow wave structure (SWS), flatted grating folded waveguide (FGFW), has been proposed for terahertz (THz) traveling wave tubes (TWTs). Compared to a conventional folded waveguide (FW ...
Abstract: This article proposes a controllable and quantizable coupling structure for ridge waveguide (WG) resonators, which is utilized to design miniatured bandpass filter (BPF) and filtering balun.
