Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...
Photons—the carriers of electromagnetic radiation—have neither mass nor electric charge. This means that light is relatively hard to control, unlike, for example, electrons, which can be ...
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 ...
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring ...
The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity.
