Light-controllable magnetic metamaterials based on loaded split-ring resonators

The paper presents a new approach for designing electromagnetic metamaterials which can be tuned by light. The results of experimental study of magnetic resonance behaviour of a tunable split-ring resonators loaded by a varactor diode and biased by a photodiode operated in photovoltaic mode are presented. The design and results of experimental investigation of light-controllable magnetic reflector array based on tunable split-ring resonators are also discussed.
