Wave-particle duality is a fundamental fact of the Universe. But we don't see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

The study of acoustic wave scattering and diffraction in waveguide structures lies at the forefront of both theoretical and applied acoustics. It encompasses the intricate processes by which sound ...

(Nanowerk News) When we encounter metals in our day-to-day lives, we perceive them as shiny. That’s because common metallic materials are reflective at visible light wavelengths and will bounce back ...

After an amazing journey, a grain from the asteroid Bennu will be brought to Diamond Light Source, the UK's national synchrotron, for scientific measurements. The grain is from 100 milligrams of ...

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 ...

(Nanowerk News) Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see fact box), except when using metal ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Inprentus provides beamline scientists with the world’s most advanced diffraction gratings for x-ray applications, offering unparalleled efficiency and high resolving power Champaign, Illinois, USA, ...
