A wireless power transfer technique that uses miniaturised receivers suitable for real-world use has been demonstrated by researchers in Korea. Hyoungjun Kim and Chulhun Seo from Soongsil University used a metamaterial slab in a resonant coupling method to significantly improve the efficiency of the power transfer, and retain this efficiency over greater distances than previously possible.
