Achieving invisibility: Cross-wavelength invisibility integrated with invisibility tactics

Invisibility is a superior self-protection strategy of long-standing interest in academia and industry, although the concept is thus far most popularly encountered in science fiction. In a new report on Science Advances, ...

Physicists 'trick' photons into behaving like electrons using a 'synthetic' magnetic field

Scientists have discovered an elegant way of manipulating light using a 'synthetic' Lorentz force—which in nature is responsible for many fascinating phenomena including the Aurora Borealis.

Painting with light: Novel nanopillars precisely control intensity of transmitted light

By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers at the National Institute of Standards and Technology (NIST) and their collaborators have reproduced with astonishing ...

True holographic movies are within grasp

Holographic movies, like the one R2D2 projected of Princess Leia in "Star Wars: A New Hope," have long been the province of science fiction, but for most of us, the extent of our experience with holograms may be the dime-sized ...

A new lens on the world: Improving the metalens with liquid crystal

For more than 500 years, humans have mastered the art of refracting light by shaping glass into lenses, then bending or combining those lenses to amplify and clarify images either close-up and far-off.

Scientists slow and steer light with resonant nanoantennas

Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put ...

Near-field light research advances particle manipulation, high resolution microscopy, and more

There are many types of light—some visible and some invisible to the human eye. For example, our eyes and brain don't have the tools to process ultraviolet light when it hits our eyes, making it invisible. But there is ...
