Graphene has had a big impact in optics and optoelectronics for both fundamental physics and real-world applications, and there is now considerable excitement about its prospects for terahertz ...

The future of wireless communications technology is fast advancing. It was only in 2019 that global operators started launching 5G. While 5G is still in the process of global implementation, 6G has ...

University of Ottawa researchers enhance THz wave frequency conversion in graphene, paving the way for advanced wireless ...

A team of researchers has developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential for faster, more efficient ...

Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of Regensburg, in ...

The resulting oscillations exert a force on the electrons in graphene. This generates a circular electron density wave that propagates through the graphene beneath the tip. The wave can reflect off ...
