We propose here the analytical and numerical evaluation of efficient power transfer through a planar layered medium of a Bessel-shaped beam (i.e., the 2-D equivalent of a Bessel beam), operating in the Fresnel region of the radiator. An analytical model is introduced together with a suitable figure of merit to estimate the amount of beam power that is efficiently transferred beyond the layered medium, by taking into account also the preservation of beam focusing in the main beam. The applications of such an approach are quite large, spanning from soil heating to near-field wireless power transfer and through-the-wall radars.

Abstract
We propose here the analytical and numerical evaluation of efficient power transfer through a planar layered medium of a Bessel-shaped beam (i.e., the 2-D equivalent of a Bessel beam), operating in the Fresnel region of the radiator. An analytical model is introduced together with a suitable figure of merit to estimate the amount of beam power that is efficiently transferred beyond the layered medium, by taking into account also the preservation of beam focusing in the main beam. The applications of such an approach are quite large, spanning from soil heating to near-field wireless power transfer and through-the-wall radars.File in questo prodotto:
