Analysis of Dispersion Characteristics of Chain of Coupled Resonators with Plasma Channel Filling and Further Design of Plasma-Beam Travelling-Wave Tubes Based on This Method
P. 63–70.
Equivalent systems method was implemented for designing the resonator slow-wave structures in plasma-beam devices, and non-impact plasma was used for the filling of the transit channel. The collation of the calculation results demonstrates the adequacy of the developed model in comparison with the real devices and structures. The analysis of the slow-wave structure dispersion characteristics was carried out. The structure of the plasma-beam travelling-wave tube high frequency unit was designed, and using the VEGA software, the tube parameters were estimated.

This study investigates the electrodynamic characteristics of "folded waveguide"-type slow-wave structures (SWSs) within the G-band (75-110 GHz) and W-band (110-300 GHz) frequency ranges. These SWSs are favored for high-frequency applications due to their advantages: higher gain, broader operating bandwidth, compact size, versatility, and simpler fabrication compared to structures like coupled cavities. Using HFSS software for ...

In this paper, axially-symmetric coupled-cavity slow-wave structures (CCSWS) in the millimeter range are investigated. Using the algorithm which allows to take into account the presence of the transit channel in the SWS, the electrodynamic characteristics for cases with and without the channel present in the model are calculated.

This article presents a three autocollimation method (TAM) for measuring the refractive index (RI) of optical glass. The popular minimum deviation method (MDM) for RI measurement is accurate, but it is very laborious, since the procedure of determining the minimum possible angle requires many iterations. TAM allows the calculation of RI based on the measurement ...

In this paper, the slow-wave structures (SWSs) of the “chain of coupled cavities”-type (CCC) were investigated. This type of SWS is widely used for designing the microwave amplifying devices due to their excellent heat dissipation properties allowing for higher output power. The influence of the transit channel, where the electron beam propagates, on the electrodynamic ...

Dispersion characteristics of optical glass are considered. An approach to research of dispersion characteristics of optical glass is proposed, requiring the measurement of the refractive index at only three wavelengths, which simplifies the measurement process compared with the use of the widely used Sellmeier equation. An approximation function for the refractive index of optical glass ...

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, ...
