Scientists build a "metagrating" filter that selects light by both wavelength and angle—unlocking next-gen AR, sensors, and ...

Intrinsic dispersion in periodic systems sets a fundamental bound for independent selectivity of resonant angles and ...

This effect enables light to travel through the system in only one direction. This "asymmetric transmission" is one of the key outcomes of this work because it can simplify telecommunication systems.

An example of hybrid technology in its purest form has been developed and built by the Fraunhofer Institute for Laser Technology (ILT) for the DVS research project “KoaxHybrid”.. In Aachen, Germany, ...

KAIST researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission.
