Researchers at the National Institute of Standards and Technology (NIST) have developed a method for evaluating and selecting optimal antenna designs for future fifth-generation (5G) cellphones, other wireless devices and base stations.

Chinese scientists shed light on the meteorological conditions responsible for the rate of icing growth on electric power transmission lines. Having a clearer understanding of what promotes icing on transmission lines during cold surges can help us better forecast and mitigate against crippling power outages caused by these events.

Researchers at the University of Extremadura have demonstrated the electromagnetic invisibility of objects using an alternative technique, based on filler cloaking. The novelty lies in achieving invisibility from the interior of the objects, without adding external layers. This approach brings numerous advantages and opens up new applications in optics, communications systems and bioengineering.

Researchers at ETH Zurich have developed a modulator with which data transmitted via millimeter waves can be directly converted into light pulses for optical fibers. This could make covering the 'last mile' up to the internet socket at home considerably faster and cheaper.

Researchers from Duke University demonstrate a new optical waveguide capable of bending photons around tight corners on a smaller scale than previously possible. The technology is made possible by through photonic crystals using the concept of topological insulators.

Steerable electro-evanescent optical refractor (SEEOR) chips take laser light in the mid-wavelength infrared (MWIR) as an input and steers the beam at the output in two dimensions without the need for mechanical devices.
