New material acts as an efficient frequency multiplier

Higher frequencies mean faster data transfer and more powerful processors—the formula that has been driving the IT industry for years. Technically, however, it is anything but easy to keep increasing clock rates and radio ...

A trick for taming terahertz transmissions

An Osaka University research team has introduced a new terahertz detector that allows extremely rapid wireless data communication and highly sensitive radar by using a frequency range that has previously been very difficult ...

A laser for penetrating waves

The Landau-level laser is an exciting concept for an unusual radiation source. It could efficiently generate so-called terahertz waves, which can be used to penetrate materials, with possible applications in data transmission. ...

Technologies for the sixth generation cellular network

Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices. For this purpose, network structures consisting of many small radio cells ...

Graphene enables clock rates in the terahertz range

Graphene—an ultrathin material consisting of a single layer of interlinked carbon atoms—is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand ...
