Proceedings of the 2017 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)
The IEEE Russia North West Section, Saint Petersburg Electrotechnical University “LETI”, National Research University of Electronic Technology "MIET", and V.A. Kotelnikov Institute of Radio Engineering and Electronics of RAS are pleased to present the Proceedings of the 2017 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (2017 ElConRus) held in St. Petersburg and Moscow, Russia on February 1-3, 2017. This conference is proudly hosted by two universities - Saint Petersburg Electrotechnical University “LETI” and the National Research University of Electronic Technology "MIET". The Organising Committee believes and trusts that we have been true to the spirit of collegiality that members of IEEE value whilst also maintaining a high standard as we reviewed papers, provided feedback and now present a strong body of published work in this collection of proceedings. The themes for this year's conference were chosen as a means of bringing together the many orientations of electrical and electronic engineering research and teaching, and providing a basis for discussion of issues arising across the engineering community in relation to electrical and electronic engineering. The aim in these proceedings has been to present high quality work in an accessible medium, for use in the teaching and further research of all people associated with electrical and electronic engineering studies. To achieve this aim, all abstracts were blind reviewed, and full papers submitted for publication in this journal of proceedings were subjected to a rigorous reviewing process. Dr. Michael Shestopalov Co-chair of the Conference Organizing Committee, Chair of the IEEE Russia NW Section Vice Rector for Research, Saint Petersburg Electrotechnical University “LETI”
In this paper, the dispersion characteristics of slow-wave structures suitable for use in devices in the terahertz range are calculated. Slow-wave structures of “winding waveguide” and “counter pins” types can be considered as suitable systems. Analysis of dispersion characteristics of slow-wave structure was carried out by a waveguide-resonator model, which is built for the slow-wave structure of “winding waveguide”-type taking into account a channel for the electron beam. Waveguide-resonator model is consisted of quadripoles which describe the waveguide segments. This model is most accurately reflects the structure of the field in the winding waveguide. Dispersion characteristics were calculated according to the program stated in this paper. These characteristics are used to construct model of millimeter traveling-wave tube, which is in this case the chain of quadripoles. The most common in the solution of these problems is the discrete approach . The difference form of electrodynamic theory of excitation is used to justify the use of a mathematical model of the discrete interaction description .
