PART 1: OPEN RESONANT SYSTEM %U https://www.dl.begellhouse.com/journals/0632a9d54950b268,793c77ac14010f19,1e4043755ca5439f.html %V 78 %X Open resonant systems as the oscillating circuits of the solid-state oscillators and characteristics of the quasi-optical oscillators themselves are the objects of the investigation. The aim of the work is to review the scientific results on the development and research of quasi- optical solid-state oscillators in the department of solid-state electronics from the inception of the idea to the development of real sources with enhanced spectral characteristics. Experimental and theoretical methods for studying the main parameters including spectrum, field topology of open resonators with resonant and non-resonant inhomogeneities are analyzed. For this purpose, the waveguide model of the resonator, the decomposition method and the generalized scattering matrix method, as well as experimental methods for measuring the spectrum, power and frequency, are used. %8 2019-03-07
