Aim of the work: elaboration of the theory foundations and numerical investigations of the above mentioned slot radiators. Method of investigations: properties of eigen oscillations and energetic parameters of the slot radiators are studied on the base of Maxwell equations, Lorenz lemma, Pointing theorem and the theory of waveguide-slot radiators, elaborated by Ya.N.Feld. The validity of eigen waves orthogonality condition is derived for the waveguide filled with a three layered dielectric, when this condition follows from the Lorenz lemma. The violation of this condition in terms of energy transfer is shown. The balance of power condition for a slot is studied in detail. The way of high accuracy roots definition from a slot is studied in detail. The way of high accuracy roots definition from a dispersion equation is elaborated. The patterns and energetic characteristics are studied for the electrically long slots when the volumes coupled and the slot cavity are filled with various dielectrics. The results of investigations can be used for the elaboration of radiation devices and parts of feeder lines accounting the real conditions of their utilization.
