When it comes to mobile phones, many people are only just making the switch from 3G to 4G, or even 5G, but those who like to keep up with the latest technology are already thinking about the next set ...

Researchers developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal. A method to analytically express ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Recently, a new technology named reconfigurable intelligent surface (RIS) is emerging as a potential candidate for 6G network. An RIS is usually designed as a reflective array equipped with a large ...

It's happened to anyone with a cell phone -- dropped calls or dead air because suddenly there is no service available. Or worse, the location pin drops on the navigation app. Researchers are looking ...
