Yury Shestopalov is a professor of mathematics at the University of Gävle, Sweden. His work mainly contributes to the spectral theory of operators and its application to electromagnetics, along with numerical and data analysis, including development of computational codes, software and program packages. He received his Ph.D. and Doctor of Science degrees in mathematics and physics from Moscow State University (MSU) in 1978 and 1988, respectively, and has accomplished a full university career from teaching assistant to professor and a department head at MSU, Karlstad University and the University of Gävle (since 2013). He has also continuously devoted himself to higher education, including establishment the MSU Kolmogorov Advanced Education and Science Center (AESC) and initiation of the Faculty of Higher Pedagogical Education at MSU, as well as participation in academic conferences and symposia. Yury Smirnov is the head of the Department of Mathematics andSupercomputer Modelling at Penza State University, Russia. His work is concerned with mathematical theory and methods for electromagnetic problems, and developing numerical methods. He received his Doctor of Science in physics and mathematics from MSU in 1995 and has served in his current position as professor since 1998. He founded a scientific school in the field of mathematical methods for solving problems of electromagnetics, and he has been honored with more than 35 grants in Russia, France and Germany. Eugene Smolkin is a docent at the Department of Mathematics and Supercomputing, Penza State University. His work primarily focuses on analysis of wave propagation in dielectric waveguides and nonlinear media. He received his Ph.D. degree in applied mathematics from the Marchuk Institute of Numerical Mathematics of the Russian Academy of Sciences (INM RAS) in 2015.
