Near-field thermal radiation is a form of thermal radiation that emerges when the distance between two bodies with different temperatures becomes smaller than the radiated wavelength. This near-field effect leads to a heat flux that surpasses that of conventional far-field thermal radiation by several orders of magnitude. This phenomenon has attracted increasing attention in recent years due to its potential for high-efficiency energy conversion at the nanoscale.
In this study, we investigated the power conversion of near-field thermal radiation using a device based on optical rectenna, which is a device that converts electromagnetic energy into electrical power. By employing rectenna-inspired structures, we conducted an analytical study on the characteristics of power conversion and the optimization of device design. The results show that near-field thermal radiation presents a very alluring avenue for the rectenna when compared to far-field thermal radiation.
