The demand for wireless communication is increasing exponentially. 6G wireless network is slated to be the successor for the present 5G wireless network technology. It includes usage of the Terahertz (THz) signal band. There have been strides in THz semiconductor and antenna technology, but there are some major issues to consider. Two of the issues of interest for implementing THz wireless communication are wireless power transmission, and beamforming to reduce information transmission losses.
Researchers at George Washington university have developed a technique to efficiently transfer both THz power and THz communication data while simultaneously doing radar imaging. The proposed technology uses a customized on-off keying modulation scheme that enables simultaneous information transfer through a nonlinear THz channel, generation of a radar-like image of the 2D space with continuous ranging to localize the target, and efficient wireless power transfer by harvesting Direct Current using a Rectenna.
