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

该提议的主要目标是开发一种在两个重要频段提供电磁(EM)能量收集的技术：微波频谱和红外频谱。在微波领域，拟议的电磁能量收集器将基于具有成本效益的印刷电路板技术。这项技术将实现远场无线电力传输，这是无线通信的自然结果。与近场能量转移形成鲜明对比的是，拟议的技术将使电子设备能够远程充电，这将在广泛的应用中显著增强移动性。考虑到土地对能源的重要性，该提案的主要内容侧重于利用先进的地表概念提高收获效率。这将有助于减少太阳能电池板收藏家所需的房地产。此外，这项技术将能够有效和高效地利用外层空间的无限能源供应，就像基于卫星的无线电力传输一样；这是一种越来越多地被主要工业化国家追求的方式。

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.
