In this contribution we address the problem of computer-aided modeling of wireless energy transfer to portable/moveable devices. By using the resonant coupling principle, two (or more) resonators may exchange energy by means of their evanescent fields. We present a new rigorous formulation for studying wireless non-radiative energy links between spherical/hemispherical resonators in free-space. The high Q hemispherical dielectric resonators are fed by coaxial lines or waveguides and the electromagnetic field is expanded in terms of spherical modes. The use of spherical transmission lines provides a rigorous network representation of the problem; moreover the presented approach is numerically very efficient thus permitting parametric investigation of the devices under test.

Abstract

In this contribution we address the problem of computer-aided modeling of wireless energy transfer to portable/moveable devices. By using the resonant coupling principle, two (or more) resonators may exchange energy by means of their evanescent fields. We present a new rigorous formulation for studying wireless non-radiative energy links between spherical/hemispherical resonators in free-space. The high Q hemispherical dielectric resonators are fed by coaxial lines or waveguides and the electromagnetic field is expanded in terms of spherical modes. The use of spherical transmission lines provides a rigorous network representation of the problem; moreover the presented approach is numerically very efficient thus permitting parametric investigation of the devices under test.
