Harvesting electromagnetic energy using metamaterial particles

A novel electromagnetic energy harvester based on Split Ring Resonators (SRR) is presented. The resonance phenomenon of SRR cells is indicative of their ability to trap electromagnetic energy from an incoming wave. This paper shows that an SRR cell can potentially be used to harvest electromagnetic energy by placing a resistive load across the gap of the resonator. To prove the concept, a prototype of a loaded single loop SRR resonating at 5.8 GHz is simulated, fabricated and tested. We show through numerical simulations that an SRR array can harvest electromagnetic energy effectively across wide range of incident angles.
