Abstract

The asymptotic expression of the current in a thin impedance vibrator disposed in an homogeneous isotropic medium with sufficiently arbitrary parameters was obtained. Expressions of vibrator near fields as functions of electrical and physical characteristics of the medium were found. Calculations were carried out and their results represented as graphs of the dependence of near field distribution on medium parameters and surface impedance of the vibrators.
