Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC ...

Engineers at the Georgia Institute of Technology have developed a new form of technology that combines two well-established technologies — a rectifier and an antenna — to create a device capable of ...

Developed by engineers at the Georgia Institute of Technology, optical rectennas use carbon nanotubes that act as antennas to capture light from the sun or other sources. As the waves of light hit the ...
