The problems of theory of narrow slots in walls of a waveguide filled with imperfect dielectric are under consideration. The power balance equation has been formulated. For the longitudinal and transverse slots in a rectangular waveguide the reflection, transfer, radiation coefficients and the part of power consumed for dielectric heating have been investigated. It is shown that the higher-mode waves make a considerable contribution into Ohm's losses which are much greater for a longitudinal slot than for a transverse one.
