Chapter 2 describes gyrotropic devices electrodynamical and mathematical models. PCh are extracted and investigated by using ANN.
Dnt galimybės models of ferrite waveguides 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 dnt galimybės in the 3rd chapter.
Multilayer SDW models are investigated in the chapter too. The results of investigation of dielectric waveguides by dnt galimybės ANN are presented there too. The usage possibilities of GDM in EM wave phase shifters, modulators, attenuators, waveguides and filters are analyzed in the 4th chapter.
