A novel slow wave structure (SWS), called double tunnel staggered grating (DTSG), which
originates from the double staggered grating (DSG) and folded waveguide (FW), is …

A novel methodology of the mode conversion between rectangular TE 10 and TE 20 mode
based on the H-plane T-junction power dividing network is proposed in this paper. A mode …

A broadband TE10–TE30-mode converter is designed and implemented using the substrate
integrated waveguide (SIW) technique, which can generate a single TE30-mode guided …

At present, there is a great interest in increasing the power level of terahertz (THz) radiation
sources. Aimed to improve the output power of sheet electron-beam devices, a sub-THz …

The design of H-band (220-325 GHz) high-order overmoded power couplers for sheet
electron beam (SEB) devices is presented in this article. The proposed power coupler was …

Traveling wave tube (TWT) is an attractive solution for wideband and high-power sources or
amplifiers in the terahertz (THz) band. In this article, a novel slow-wave structure (SWS) for …

In this work we construct the first-principles theory for the near-field resonances arising in the
system of two different coupled nanoparticles excited by the external field. The obtained …

Two power coupling structures based on a Y-type branch waveguide (YTBW) coupler for
sheet electron beam devices are presented in this paper. The YTBW coupler is a good …

A novel methodology of the power coupling from rectangular TE 10 mode to TE 20 mode for
high-order overmoded multiple sheet electron beam devices is presented in this letter. The …

A novel concept of combining the advantages of pseudospark (PS)-sourced electron beam
(high beam current density), multiple-sheet-electron-beams (large total beam cross …
