Fesenko V. Electromagnetic waves in multicomponent artificial composite media

The thesis is related to a new field of modern radiophysics, which concerns with the synthesis of artificial composite structures and theoretical and experimental study of their electromagnetic properties. The structures under study are composed of optically active components and can operate on the same physical principles in different frequency ranges from microwave to visible. The aim of the work is to develop and analyze, in the framework of a unified theory, several physical and mathematical models of the electromagnetic field interaction with artificial composite media. In the proposed models, the effects of anisotropy and spatial inhomogeneity on the characteristics of electromagnetic wave propagation in the studied artificial structures are accounted for. The author develops and generalizes the existing methods of analysis of artificial structures with complex spatial composition. These methods combined with other approaches of modern radiophysics and mathematical physics allow revealing a number of new physical conditions and effects of propagation and scattering of electromagnetic waves in such composite structures. The results obtained in the thesis are important for both theoretical and applied physics with the aim to design highly efficient devices for photonics, microelectronics, optoelectronics, and plasmonics, and for deepening fundamental knowledge about the interaction of electromagnetic waves with artificial composite media.
