Instead of using traditional glass mirrors or lenses, MOIRE (Membrane Optical Imager for Real-Time Exploitation) seeks to diffract light with Fresnel lenses made from a lightweight membrane roughly ...

Seventy years after scientists first proposed such an experiment, researchers from the University of Nebraska in Lincoln have shown light waves can diffract or bend a beam of electrons. The study ...

Diffractive robotics platform (A) 10×10 mm chip containing arrays of diffractive robots. (B) Close-up view of robots with varying sizes and numbers of panels. Scale bars, 50 µm. (C) False-coloured SEM ...

From magnetic drawing toys to grade-school science demonstrations, tiny particles of iron oxide can be delightfully entertaining when subjected to magnetic forces. Modify the particles a bit via ...

Results: A team from the University of California, Berkeley, has devised a silver “superlens” that could increase the resolution of light microscopy by about a factor of six. The lens doesn’t diffract ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Physicists have taken a step toward making 'metalenses' even more useful -- by making them reconfigurable. They did this by harnessing nanoscale forces to infiltrate liquid crystals between those ...

An international team of researchers has made tunable, extremely lightweight lenses using graphene (ACS Photonics 2015, DOI: 10.1021/ph500197j). The lenses act like microscopic versions of ones used ...
