Abstract: The concept of metagratings is a powerful means to control diffracted electromagnetic fields by accurately engineering the near-field. In this letter, a bifunctional metagrating that can ...

When I started waterfowling in 1974—and back then, it was simply known by the all-inclusive term “duck hunting“—we didn’t have blind bags, the modern day equivalent of carry-on luggage for duck and ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Is it possible to 3d print a diffraction pattern? People in Denmark 'stunned' by Trump's Greenland comments, former ambassador says Tenacious D's Kyle Gass addresses controversial Trump joke and Jack ...

"Diffraction effects and polarization-related reflections make it difficult to control how energy is distributed during ablation," says Prof. Shaolin Xu, a laser manufacturing expert at SUSTech and ...

One longstanding problem has sidelined life-saving drugs, stalled next-generation batteries, and kept archaeologists from identifying the origins of ancient artifacts. For more than 100 years, ...

When designing a kitchen, the hard surfaces tend to take priority. Countertop materials, cabinetry, and appliances are what help your kitchen perform to the max. But don't overlook the decorative ...

This novel finding regarding the nonreciprocal diffraction of acoustic waves could open doors for next-generation communication devices. A unique propagation phenomenon of acoustic waves has been ...
