Electromagnetic Wireless Power Transfer and Harvesting in the Microwaves and Infrared Frequency Regimes

点击翻译按钮获取中文摘要

The proposal primary goal is to develop a technology that provides electromagnetic (EM) energy harvesting in two important frequency bands: The microwaves spectrum and the infrared spectrum. In the microwaves spectrum, the proposed EM energy harvesters will be based on cost-effective printed circuit board technology. The technology will enable far-field wireless power transfer which is a natural consequence to wireless communications. In stark contrast to near-field energy transfer, the technology proposed will enable remote charging of electronic devices which would enhances mobility significantly in a wide range of applications. Considering the importance of land to energy in general, key elements of the proposal focus on increasing the harvesting efficiency using advanced metasurface concepts. This will help reduce the real-estate needed for panel collectors. Additionally, the technology will enable effective and efficient tapping of the unlimited supply of energy from outer space as in satellite-based wireless power transfer; a modality that is being increasingly pursued by leading industrial nations.
