Rectenna systems harness electromagnetic radiation by integrating an antenna with a high‐speed rectifier diode to convert incident waves—ranging from microwaves to infrared—directly into electrical ...

When we think of solar-based energy, we usually associate it with electricity-generating solar cells; solar-based heating systems using a working fluid; solid-state thermoelectric-based conversion; or ...

Using multiwall carbon nanotubes, researchers at Georgia Institute of Technology have created what they say are the first optical rectennas–antennas with rectifiers that produce DC current. The work ...

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 ...

Rectifying antennas – "rectennas" – are used as parasitic power capture devices that absorb radio frequency (RF) energy and convert it into usable electrical power. Constructing such devices to absorb ...
