چکیده

In this article, we investigate a compact metamaterial structure for enhancing magnetic resonant wireless power transfer (WPT) system operated at 6.5 MHz. A thin (MM) slab placed between the transmitter (Tx) and receiver (Rx) coil can improve WPT efficiency. The unit cell is designed by ten-turn spiral resonator (10T-SR) loaded with an external capacitor. frequency of MM cells be easily controlled changing capacitor value. By using optimization approach, achieve significant efficiency improvement mid-range distance. results showed enhancement field in when was present. This demonstrates ability to amplify evanescent wave slab, thereby improving transmission coefficients 60 cm increased from 0.5 0.76 which corresponds 46% improvement.

Resonant cavity mode enabled wireless power transfer

This letter proposes using the electromagnetic resonant modes of a hollow metallic structure to provide wireless power to small receivers contained anywhere inside. The coupling between a large chamber (used as a cavity resonator) and a small wire loop (used as a receiver) is studied. An analytic expression for the coupling coefficient between the fields in the cavity and a loop receiver is der...
