On the Arbitrary Control of Passive Magnetic Metasurfaces Response

In this paper, an analytic circuital approach to manipulate the response of magnetic metasurfaces is introduced. In particular, we show that the control over the current flowing in each array element can be arbitrary, thus allowing exotic properties accomplishment. For instance, we prove that beam-steering capability can be easily achieved. The reliability of the proposed analytical model is proved performing full-wave simulations over a test-case configuration. The accurate control on the overall metasurface response can be extremely significant in a number of applications, such as resonant inductive Wireless Power Transfer, reconfigurable antennas and Magnetic Resonance Imaging.
