Information × Registration Number 0122U000667, R & D request Title Investigation of the processes of formation, propagation and radiation of powerful electromagnetic pulses and polarized waves of the GHz, terahertz and optical ranges in frequency-selective structures and metamaterials and their interaction with biological objects Head Pazynin Vadym L., Доктор фізико-математичних наук Registration Date 28-01-2022 Organization O. Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description1 The purpose of the work is theoretical and field modeling and in detailed study of the scattering of pulsed and monochromatic electromagnetic waves by waveguide, periodic and open resonant structures, in solving fundamental radiophysical problems with a clear applied orientation, and in obtaining new knowledge for radio physics and electronics; the model search for designs of active and passive compressors of electromagnetic pulses (and their individual components), which in the case of their full-scale implementation would allow to obtain compressed pulses with unique characteristics; building rigorous mathematical models of the propagation of electromagnetic waves in negative environments, which would allow to obtain analytical solutions; the development of basic elements of devices that can effectively operate with giga- and terahertz fields: multi-band irradiators and frequency and polarization-selective elements, quasi-optical resonators, dielectrometric cuvettes; the study of changes that occur in biological tissues, in particular, human tissues in their interaction with electromagnetic fields of the gigahertz and terahertz ranges; the creation of the latest devices for microscopic analysis of dielectric and morphological changes in cells by optical diffraction microscopy popup.nrat_date 2024-12-09 Close
