UrduMetasurfaces are formed by engineering a glass surface with an array of microscopic features, or meta-atoms. Although different optical functionalities can be obtained by changing only the pattern, the resulting metasurfaces often lack the necessary efficiency for many applications. In this report, scientists from Corning and Harvard University collaborate to demonstrate an inverse-design method that optimizes efficiency while respecting fabrication constraints. These results represent a step forward in making practical metasurfaces for broader applications.

Silicon chip propels 6G communications forward
A team of scientists has unlocked the potential of 6G communications with a new polarisation multiplexer.
Terahertz communications represent the next frontier in wireless technology, promising data transmission rates far exceeding current systems.
By operating at terahertz frequencies, these systems can support unprecedented bandwidth, enabling ultra-fast wireless communication and data transfer. However, one of the significant challenges in terahertz communications is effectively managing and utilising the available spectrum.
The team has developed the first ultra-wideband integrated terahertz polarisation (de)multiplexer implemented on a substrateless silicon base which they have successfully tested in the sub-terahertz J-band (220-330 GHz) for 6G communications and beyond.
