Abstract :
The problem about radiation of electromagnetic waves by the thin vibrator with the symmetrical and antisymmetrical components of the surface impedance relative to its centre, where the point source of excitation is located, has been solved by the generalized method of induced electromotive forces. The analytical expressions, obtained in a closed form, allow to obtain the current distribution along the vibrator length and to calculate its electrodynamic characteristics. The calculations of the vibrators input parameters of different electrical length, dependent of the values of both symmetrical and antisymmetrical components of the vibrator surface impedance, have been made.
