The cascade backward-wave amplifier (CBWA) has gained recent interest as amplifier at terahertz frequencies. The backward-wave regime permits the design of slow wave structures (SWSs) with longer period and geometrical dimensions, for a given frequen

A dual-mode horn antenna with a vacuum window for 1040 GHz has been designed. Simulations indicate a near-Gaussian far-field pattern, an average half power beamwidth of 2.7° and sidelobes lower than −35 dB. The horn can be used in the input/output

A novel slow-wave structure (SWS), created for THz vacuum tubes, based on two parallel corrugations in a rectangular waveguide, realizes the conditions for a quasi-cylindrical field distribution, to support the interaction with a circular beam. A des
