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 ...

The pattern may be bigger, and red light is likely less sensitive to imperfections in the grating. Some of the special edition banknotes in circulation don't have the maple leaf diffraction grating.

Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

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

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.

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.

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 ...

The magnetic nanoscale array can be thought of as a specialized grating that the waves go through. To their surprise, instead of the typical symmetric diffraction pattern, the research team ...
