近接場エネルギーを用いてワイヤレスでエネルギーを伝送するための機器

Title:

近接場エネルギーを用いてワイヤレスでエネルギーを伝送するための機器

Document Type and Number:

Japanese Patent JP2014518059

Kind Code:

A

Abstract:

Techniques are described for wireless energy transmission and projecting magnetic fields over relatively long near-fields. In one example, a device for transmitting near-field energy comprises at least one source that generates a radiofrequency (RF) signal, an antenna that generates near-field signals from the RF signal, and a plurality of sub-wavelength sized elements that form a lens in communication with the antenna that captures the near-field signals, generates near-field energy, and re-directs the near-field energy toward an object in the near-field of the lens, where the sub-wavelength sized elements are disposed about the antenna.
