Abstract: The present disclosure provides wireless power transfer systems and methods. One such system includes a transmitter comprising a transmitter coil coupled to a power source and a transmitter metasurface slab positioned on a front side of the transmitter coil that is configured to amplify and focus a magnetic field generated by the transmitter coil towards a receiver in a non-contact manner. In such a system, the receiver comprises a receiver coil coupled to a load and a receiver metasurface slab positioned on a front side of the receiver coil configured to amplify and focus a magnetic field generated by the transmitter coil towards the receiver coil in a non-contact manner. Other systems and methods are also provided.

Abstract: The present disclosure describes various embodiments of systems, apparatuses, and methods of fabricating a metamaterial-inspired dual-function loop antenna. One such antenna device comprises a loop antenna and a metamaterial slab integrated on top of the loop antenna. Accordingly, the metamaterial slab metamaterial has a negative refractive index value at a first frequency and a near zero refractive index at a second frequency, wherein the first frequency is less than the second frequency, each unit cell of the metamaterial slab is coupled to a capacitor in parallel, the first frequency is attributed to a capacitance value of the capacitor, and the second frequency is attributed to a dimension of the unit cell. As such, the antenna device is configured to receive wireless power transfer signals over the first frequency and wireless communication signals over the second frequency. Other apparatuses, systems, and methods are also presented.
