A nanoscale 3D structure to control light

Metamaterials, made up of small, repeated structures, engineered to produce desired interactions with light or sound waves, can improve optical devices used in telecommunications, imaging and more. But the functionality of ...

Metasurfaces control polarized light at will

For years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research has contributed to advances ...

Tunable 'metasurface' is akin to optical swiss army knife

MIT engineers and colleagues report important new advances on a tunable metasurface, or flat optical device patterned with nanoscale structures, that they compare to a Swiss army knife while its passive predecessor can be ...

Novel microscopy method provides look into future of cell biology

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically ...

New biosensor designed to detect toxins and more

A device from Los Alamos National Laboratory researchers is not quite the Star Trek "tricorder" medical scanner, but it's a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) ...

Graphene 'smart surfaces' now tunable for visible spectrum

Researchers at The University of Manchester's National Graphene Institute have created optical devices with a unique range of tunability, covering the entire electromagnetic spectrum, including visible light.
