Abstract

A problem of electromagnetic waves excitation by a structure, consisting of a narrow transverse slot in a broad wall of a rectangular waveguide and a vibrator with variable surface impedance, located inside the waveguide, is solved by the generalized method of induced electro-magneto-motive forces. Conditions, necessary for achievement of maximal slot radiation coefficient are defined. Calculated and experimental plots of energy characteristics of the vibrator-slot structure for different vibrator placement relative to the slot and for various dependencies of surface impedance upon the vibrator length are presented.
