“…In order to reduce the tube size and dimensions, as well as the dc voltage, planar microstrip meanderline SWS on dielectric substrates have been proposed. We fabricated SWS circuits in V-and W-band using the novel technology utilizing magnetron sputtering and laser ablation methods [7]. Several samples of Vband and W-band meander SWS circuits on quartz substrates were fabricated.…”

“…В работах [10][11][12] нами были разработаны планарные ЗС типа встречные штыри и меандр на диэлектрических подложках из кварца в V -диапазоне (50−70 GHz), проведены теоретическое и экспериментальное исследования их электродинамических параметров. В настоящей работе исследуется возможность разработки подобных ЗС более высокочастотного W-диапазона (75−110 GHz).…”

The research results of a miniature meander planar slow-wave structure (SWS) for W-band traveling wave tube are presented. 3D computer simulation of the electrodynamic parameters of SWS has been carried out. A new technology of manufacturing of planar microstrip SWS has been presented. An experimental research of the S-parameters of an SWS has been carried out. The results show good agreement with the results of 3D simulation. The output characteristics of the TWT with sheet electron beam and planar SWS on dielectric substrate were simulated.

“…In recent years, a variety of planar SWSs have been studied for millimeter-wave and terahertz SB-TWTs, including a 0.22 THz double-staggered grating waveguide (DSGW) [11], a Ka-band three-slot double-periodic staggered-ladder coupled-cavity [12], a G-band copper grating [13], a V-band microstrip meander [14], and a W-band sine waveguide [15]. Among these planar SWSs, the DSGW SWS has exhibited an intrinsically wide bandwidth and high power capacity.…”

Shenzhen University (2018046).Abstract-The design, fabrication and cold test of a high frequency system (HFS) for an H-band (220-325GHz) sheet beam travelling wave tube (SB-TWT) is presented in this paper. The HFS was composed of a 90-period double-staggered grating waveguide and a pair of identical L-shaped couplers with Bragg reflectors and matching steps. The HFS was manufactured by Nano-CNC machining and its electromagnetic properties were measured by using a vector network analyzer. The measured S-parameters were in good agreement with the simulated ones, which predicted a 3 dB bandwidth of ~47.0 GHz. The maximum value of the measured transmission coefficient S21 was -4.9 dB and the in-band port reflection S11 was around -15.0 dB. Based on the cold testing-based HFS, simulations of the beam wave interaction predicted a stable output power of over 55.1 W in the frequency range of 230-280 GHz. In addition, the instabilities of the beam wave interaction were investigated in the simulation.Index Terms-high frequency system, interaction instability, terahertz wave amplification, sheet beam travelling wave tubes.
