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.

Design of a Compact Planar Rectenna for Wireless Power Transfer in the ISM Band
International Journal of Antennas and Propagation, 2014 This paper presents a compact planar rectenna with high conversion efficiency in the ISM band. The proposed rectenna is developed by the decomposing of a planar rectenna topology into two functional parts and then recombining the two parts into a new ...

A carbon nanotube optical rectenna [PDF]
Nature Nanotechnology, 2015 An optical rectenna--a device that directly converts free-propagating electromagnetic waves at optical frequencies to direct current--was first proposed over 40 years ago, yet this concept has not been demonstrated experimentally due to fabrication challenges at the nanoscale. Realizing an optical rectenna requires that an antenna be coupled to a diode
