A goal of this work is to flnd a possible explanation of the experimental results of (1) where the wireless power transfer between two coils is investigated. We show that this wireless power transfer is provided by the longitudinal component of the EM fleld. Using Jeflmenko's approach of solving the Maxwell equations we show that under speciflc conditions the longitudinal component drops with the distance as 1=R. This result dependence can explain the experimentally detected dependence of the transferred power in the experiment.
