Development of adaptive tracking algorithms for maneuvering targets in the radar coordinates. Construction of novel mathematical models and physical fundamentals of designing metamaterials and SMART meta-surfaces and investigation diffraction characteristics periodic structures of dispersive magnetic elements of complex geometries, and also development of physical principles of controlling the reflections of meta-surfaces with magnetic insertions. Development of new methods and algorithms for solving numerically the respective equations for calculation of the characteristics of multiple scattering of emission by discrete random media with allowance for the wave weak localization effect. Improvement of the model for the central regions of the galactic active nuclei with account of the central machine emission and interaction with surrounding environment. popup.nrat_date 2024-12-09 Close
