A. A. Vikharev,G. G. Denisov,Vl. V. Kocharovskiĭ,Sergey Kuzikov,Vladimir V. Parshin,N. Yu. Peskov,A. N. Stepanov,Dmitry I. Sobolev,M. Yu. Shmelev +8 more
TL;DR: In this article, a new microwave switch was proposed, in which the active element represented a metal reflector with a semiconductor plate on a mirror surface, and the wave beam phase switching was ensured by a conducting layer formed in the semiconductor by laser radiation with quantum energy approximately equal to the bandgap width.
Journal ArticleDOI
Efficiency Enhancement of Components Based on Talbot Effect
TL;DR: In this paper, two ways to increase efficiency of components based on Talbot effect are considered: optimization of waveguide wall impedance and corrections of the waveguide cross-section, and it is shown that for many cases undesired scattering losses can be made several times less than that for usual cases of infinite of zero impedance and rectangular waveguide crossing-section.
Journal ArticleDOI

TL;DR: In this article, the possibility of using the technology of 3D photopolymer printing with subsequent metallization of working surfaces for developing electrodynamic components of microwave devices was studied.
Proceedings ArticleDOI
Study of Ka-band components for a future high-gradient linear accelerator
G. G. Denisov,A.G. Litavk,M. I. Petelin,A. L. Vikharev,S. V. Kuzikov,A.M. Gorbachev,V. G. Paveliev,A.A. Bogdashov,M. Yu. Shmelev,Jay L. Hirshfield +9 more
TL;DR: In this article, results of investigations of many components including resonator passive pulse compressor, controllable launcher for a DLDS system, low-loss miter bends, and mode converters are presented.
Journal ArticleDOI
Boosted excitation of the fifth cyclotron harmonic based on frequency multiplication in conventional gyrotrons.
Gregory G. Denisov,Irina V. Zotova,Andrey M. Malkin,A. S. Sergeev,Roman R. Rozental,Andrey P. Fokin,V. I. Belousov,M. Yu. Shmelev,A. V. Chirkov,Alexander I. Tsvetkov,Ilya V. Bandurkin,M. Yu. Glyavin +11 more
TL;DR: In this paper , a specific property of the eigenmodes of a cylindrical waveguide was discovered, due to which efficient mode excitation at ultrahigh (s=4n+1, n is integer) multiples of the gyrofrequency can be provided by a polyhelical weakly relativistic electron beam, standardly used for gyrotron operation.
