110 GHz gyrotron with a built-in high-efficiency converter
Gregory G. Denisov,A. N. Kuftin,V. I. Malygin,N. P. Venediktov,D. V. Vinogradov,V. E. Zapevalov +5 more
TL;DR: In this article, a 110 GHz 1 MW pulse gyrotron with a built-in electrodynamic duct consisting of a new type quasi-optical converter and three matching mirrors transforms operating mode TE15,4 into a gaussian beam going through the output window.
Journal ArticleDOI
Mirror synthesis for gyrotron quasi-optical mode converters
A.A. Bogdashov,A. V. Chirkov,Gregory G. Denisov,D. V. Vinogradov,A. N. Kuftin,V. I. Malygin,V. E. Zapevalov +6 more
TL;DR: In this article, a new approach for the design of a quasi-optical gyrotron mode converter is proposed based on the synthesis of quasioptical mirrors using diffraction (Helmholtz-Kirchhoff) integrals.
Journal ArticleDOI
Selective excitation of high-order modes in circular waveguides
N. L. Aleksandrov,A. V. Chirkov,Gregory G. Denisov,D. V. Vinogradov,W. Kasparek,J. Pretterebner,D. Wagner +6 more
TL;DR: In this article, the excitation of very high-order modes in circular waveguides has been performed in a cavity with a connected up-taper with a geometry similar to those used in gyrotrons.
Journal ArticleDOI
Waveguide mode converters with step type coupling
D. V. Vinogradov,G. G. Denisov +1 more
TL;DR: In this paper, the authors propose a new mode of modes of change in a mode of change that is based on the mode of the mode in which the mode is used by the user.
Journal ArticleDOI
Mirror conversion of gaussian beams with simple astigmatism
TL;DR: The surface of an inclined mirror, which converts Gaussian beams with simple astigmatism, has been found within the quasi-optical approximation as mentioned in this paper, and the beam reflected from the found mirror was examined.
