A wearable metasurface for high efficiency, free-positioning omnidirectional wireless power transfer

A wearable metasurface for high efficiency, free-positioning omnidirectional wireless power transfer

We introduce a design principle of metasurfaces that can form any desired distribution of magnetic field for high-efficiency wireless power transfer centered at 200 kHz, which can be used to efficiently charge implanted medical devices. This metasurface can improve the power transfer efficiency for...
