Karazin popup.description2 The object of investigation is pulse electromagnetic field. The subject of investigation is process of pulse signals interactions with dispersive medium under conditions of bounded volume and free space. The aim of investigation is development of mathematical models, computa-tional methods, algorithms and their software implementations for studying proc-esses of short pulse signals interaction with dispersive medium, revealing new physical phenomena that occur in the structures under study, investigation of pos-sibilities to develop new radiophysical devices on this base. The method of investigation. Several problems about transient electromag-netic fields in different structures has been solved. In particular, transient and sta-tionary oscillations in a cavity filled with dispersive medium have been studied. Separately, a cavity with medium that has negative refractive index was investi-gated. Problems of diffraction on a layer of conductive medium were solved in time domain based on method of mode basis. A method has been proposed for cal-culating propagation of a pulse wave beam and its diffraction on a dielectric half-space of dispersive medium. Change in the dispersion law of medium when placed in a heterogeneous mix has been investigated. Product Description popup.authors Антюфеева М. Грідіна В. Демченко О.
