Karazin popup.description2 The systems under consideration consist of slot coupling elements in a waveguide with longitudinal dielectric layer, in a waveguide with nonideal walls, impedance diaphragms, three-slot rejecting philters with dielectric inser-tions. The possibility of replacement during the slots parameters calculations of explicit far roots values of dispersion equations for LE-, LM-waves and poten-tial functions with their approximate values obtained from asymptotic expres-sions. The possibility of frequency range properties control of a scanning waveguide-slot antenna based on a waveguide with longitudinal dielectric layer was investigated using the slots resonance frequency variation. The typical features of radiation process of electrically long slots and of radiation from the waveguide open end into free half-space filled with ideal or dissipative dielec-tric are studied.
