Rectennas for thermal-energy conversion [PDF]
2014 39th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2014 We demonstrated the conversion of thermal energy in the form of far- and mid-infrared using a micro rectenna, consisting of a spiral antenna coupled to an ultra-fast nanodiode, the so-called self-switching device (SSD). A maximum efficiency of 0.02 % was measured at a 973 K (700 °C) using a calibrated black-body radiator illuminating the rectenna.
