Electromagnetic fields excitation by multi-element vibrator-slot structure in rectangular waveguide

A problem of electromagnetic fields excitation by a structure, consisting of a narrow transverse slot in a broad wall of a rectangular waveguide and two asymmetrical vibrators with variable surface impedance, located inside the waveguide, is solved by the generalized method of induced electro-magneto-motive forces (EMMF). Calculated and experimental dependencies of energy characteristics of the vibrator-slot structure for different vibrators placement relative to the slot and for various dependencies of surface impedance upon the vibrators length are presented.
