Researchers show use of MFRE can at least double wireless power transfer efficiency; more efficient than metamaterials

Green Car Congress

Researchers at North Carolina State University and Carnegie Mellon University have shown that passing wireless power transfer through a magnetic resonance field enhancer (MR-FE)—which could be as simple as a copper loop—can at least double transfer efficiency as compared to transferring through air alone. MR-FE use could potentially boost transfer efficiency by as much as 5,000% in some systems, the researchers said.
