Wireless transmission of power from point to point has been developed in two predominate electromagnetic frequency ranges: near-infrared and microwave. In this paper, the prospect of wireless power beaming in the terahertz frequency range is explored with emphasis on the role of adverse weather. Link distance, power transmission, and safety performance of near-infrared, microwave, and terahertz power beaming are compared under clear and adverse weather conditions. While infrared power beaming provides the longest link distances of the three under clear weather conditions, terahertz power beaming can provide better performance under adverse weather conditions.

晴天和不利天气条件下太赫兹，微波和激光功率光束的比较

已经在两个主要的电磁频率范围内开发了从点到点的无线功率传输：近红外和微波。在本文中，着眼于不利天气的作用，探索了太赫兹频率范围内无线电力发射的前景。在晴朗和不利的天气条件下，比较了近红外，微波和太赫兹功率波束的链路距离，功率传输和安全性能。尽管在晴朗的天气条件下，红外功率发射可以提供三者中最长的链接距离，但是在不利的天气条件下，太赫兹功率发射可以提供更好的性能。
