Improving the metalens with liquid crystal – Tech Explorist

The Nanostructured metamaterials have been engineered to generate a wide range of optical phenomena, allowing unprecedented control over light propagation. However, they are generally designed as single-purpose devices without a modifiable optical response, which can be a barrier to applications.
In a new study, scientists took a step toward making these metalenses more useful by making them reconfigurable.
Case Western Reserve University physics professor Giuseppe Strangi and collaborators at…
