Near region field of antennas in piecewise-homogeneous media

The mutual effect of electric dipoles located in the near region of each other is considered. The problem is solved with due account of that the space is a heterogeneous medium with an equivalent permittivity. Calculations are based on the theory of folded dipoles. It is shown that by means of a compensation method one can produce a weak field in a given area and diminish a user´s irradiation. The calculation and experimental results are presented and validate the high efficiency of the compensation method.
