Electromagnetic waves scattering by thin impedance vibrators and narrow slots in waveguides

The system of integral-differential equations relative to the surface ones of the equivalent magnetic current on the coupling hole of the electromagnetic volumes and the electrical current on the impedance body of finite sizes, induced by the set impressed sources of the electromagnetic field, has been obtained. The approximate analytical solution of the obtained equations system for the narrow slot in the broad wall of the rectangular waveguide, in which the thin impedance vibrator, which does not partition off the waveguide completely, is located, is given.
