Maxim A. Dubovitsky graduated with honors from the Master's degree program of the National Research University "Moscow Power Engineering Institute" in 2018 with a degree in Radio Engineering. In 2018, M.A. Dubovitsky entered the graduate school of the National Research University "MPEI" in the specialty "Antennas, microwave devices and their technologies" with the topic of his PhD thesis "Creation of a methodology for designing low-element arrays of sharply directional antennas for solving problems of aperture synthesis of space-based radio systems". During his studies, he was the recipient of scholarships from the Scientific Council of the National Research University of the "MPEI" (2019-2020), the Government of the Russian Federation (2020) and the President of the Russian Federation (2021-2022). In 2021, he was awarded the gratitude of the Ministry of Science and Higher Education of the Russian Federation for his significant contribution to the development of the field of education and many years of conscientious work. Developer of small-sized space antennas of a new generation for operation in the S-, C-, X-, Ku- and Ka-frequency bands. Work experience in the framework of R&D (including for a State Customer and a foreign Customer) for more than 8 years (from the development to the support of production). Key skills include developing effective antenna solutions for various applications, utilizing advanced software tools for analyzing and optimizing their performance, such as Ansys HFSS, Altair Feko, and Matlab.

• Development, simulation, design and tuning of microstrip on-board antennas, reflector antennas, phased antenna arrays and feeds of ground-based antenna systems (Software: CAD and CAE: Ansys/Altair/CST/Ticra/Matlab); • Development of design (PDR and CDR), working design and operational documentation for antenna systems, development of technical specifications for the components of the system to co-executors, calculations, development of test programs, preparation of reports, preparation and coordination of technical specifications of products, manuals, setup instructions, programs and methods of measurement and testing for antenna systems; • Measurement of electrical characteristics of antenna perfomance (Hardware: Signal Analizer and Network Analizer: Rohde & Schwarz/Agilent/Keysight/Anritsu); • Supervising the work of co-executing organizations (coordination of documentation, supervision of contracts on the technical part, conducting business correspondence).
The research project expects the results of analytical calculation and their comparison with the char- acteristics obtained by electrodynamic modeling in the software packages CST Microwave Studio, Altair FEKO, as well as mathematical programming devices MATLAB, Python and Julia. Among the expected results, we can distinguish: - creation of a mathematical model of antenna arrays, developed on the basis of a system analysis of the technical features of radiating structures and allowing to describe antenna array composed of aperiodic subarrays; - patent research and verification of the patent purity of the developed products and software planned for patenting has been provided; - development of a method for optimizing the placement of subarrays with a number of elements up to 256, based on modernized evolutionary genetic algorithms (registration of a patent for a utility model); - software for solving the problem of optimizing the structure of antenna arrays, based on the proposed algorithm and allowing you to design antenna arrays in the terahertz frequency range (registration of a patent for a computer program); - simulation electrodynamic model - simulation results showing the effectiveness of the pro- posed algorithm and the structures of antenna arrays obtained with its help, allowing for a comparative analysis with achievements in the field of digital phased antenna array design; - determination of the main dependencies of the spatial characteristics of MIMO-type antenna arrays on the design parameters of their elements. If a number of hypotheses are proved, these dependencies can form the basis for creating a universal mathematical apparatus for calculating non-equidistant inhomogeneous antenna arrays of arbitrary shape. - the MATLAB program was implemented, the main task of which is to perform conditional minimization of a given function of several variables based on the use of a genetic algorithm.
3rd IEEE Nordic Student and Young Professionals Congress. The congress venues took in the vibrant Aalto University in Helsinki, which share with an alumni student weekend and the historic KTH university in Stockholm. This event gave an unique opportunity to grow global networks and to get new ideas. It was expected to see 50 Young Professionals and Students during the week from all around Region 8. The program included interesting IEEE presentations, workshops and team building activities. The participants had a great opportunity to listen to interesting presentations and panel-discussions from professionals working both in industry and academia. The topics discussed during this event include e.g. smart cities, electric vehicles, energy storages and improved energy efficiency.
