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.
Kasatkin A., Kravchenko N., Mukhin S., Presnyakov S.

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.

A Three Autocollimation Method for Measuring the Refractive Index of Optical Glass
Yurin A., International Journal of Applied Glass Science 2026 Vol. 17 No. 2 Article e70022
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 ...
