Models of gyrotropic devices ; semiconductor and semiconductor-dielectric dnt galimybės ; phase shifters and modulators ; attenuators Abstract [eng] An improvement of gyrotropic devices models GDMpropagating electromagnetic EM wave characteristics and parameters research prediction, and problems of model application are discussed throughout the work. An object of the research is GDM and their usage possibilities.
The aim of this dissertation is to investigate Dnt galimybės wave phase and attenuation characteristics PCh, AChparameters, and the possibilities of models usage.
Dnt galimybės dissertation consists of four parts including Introduction, 4 dnt galimybės, Conclusions, References and 3 Annexes.
The introduction reveals the investigated problems, dnt galimybės importance of the thesis and the object of research. It also describes the purpose and tasks of the work, research methodology, scientific novelty, and the practical significance of results examined in the work and defended propositions.
Chapter 1 revises the literature used throughout the dissertation. At the end of the chapter, the conclusions are drawn and the tasks for the dissertation are reconsidered. Chapter 2 describes gyrotropic devices electrodynamical and mathematical dnt galimybės.
PCh are extracted and investigated by using ANN. Physical models of ferrite dnt galimybės are investigated experimentally. The wave PCh of SDW models, as well as wave PCh and ACh of waveguides with temperature sensitive semiconductor core and anisotropic dielectric layer are analyzed in the 3rd chapter.
Multilayer SDW models are investigated in the chapter too. The results of investigation of dielectric waveguides by using ANN are presented there too.
The usage possibilities of GDM dnt galimybės EM wave phase shifters, modulators, attenuators, waveguides and filters are analyzed in the 4th chapter.
