Abstract: A method for controlling radiation scattering, comprises: directing radiation to a metamaterial having an array of individually tunable and near field coupled resonators, varying an individual resonance frequency of at least one of the resonators to provide a collective resonance scattering of the radiation by the metamaterial, measuring a scattering signal of the collective resonance scattering of the radiation, and identifying the metamaterial based on the scattering signal.

Abstract: An antenna system comprises an antenna array having a plurality of antenna elements each having a resonator configured for emitting non-optical radiation, and a resonance tuning device for tuning a resonance frequency of the resonator. The antenna system also comprises an optical array having a plurality of light activated devices respectively aligned with the plurality of antenna elements, and a network of waveguides arranged to guide light to each light activated device. Each activated device provides electrical energy to a respective resonance tuning device upon activation by light via a respective waveguide.

Abstract: A cloaking and/or deception system comprises: a structure having a plurality of resonators characterized by a controllable resonance frequency, wherein the resonators are arranged to collectively ensure that variation of the resonance frequency over a predetermined range of resonance frequencies generates a phase shift between the an electromagnetic wave incident on the structure and an electromagnetic wave scattered off the structure; and a controller configured for controlling the resonance frequency to provide a time-varying resonance frequency characterized by a temporal function which comprises a linear time-dependence.
