Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

However, using an atom-thick layer of carbon atoms known as graphene, experts found that even after 100 hours under irradiation of an atom beam, the grating showed no damage and diffraction still ...

Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not. [Renaud] pulls off this ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication ...

The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.

The discovery of asymmetric diffraction in acoustic waves opens new avenues for innovative communication devices, impacting ...

and Λ is the grating period. The efficiency has a well‐defined dependence on polarization. In particular, it is possible to obtain theoretical 100% diffraction efficiency with one linear polarization ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th century, scientists realized it was both: massless particles and waves.

By imaging the grating holographically, we retain tremendous flexibility in design as well as precise parameter control, allowing us to generate very high quality, highly custom diffraction gratings ...
