Diffraction is a fundamental wave phenomenon. It manifests itself for light waves in almost all optical systems, limiting our ability to focus or collimate light beams. Due to diffraction, it is ...

How matter responds to light lies at the core of vision, photosynthesis, solar cells, and many other fields of scientific and practical import. But until now, it hasn't been possible to see just how ...

SIAM Journal on Applied Mathematics, Vol. 48, No. 1 (Feb., 1988), pp. 1-37 (37 pages) We derive an asymptotic partial differential equation which describes the diffraction of a weakly nonlinear high ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

The first neutron interferometer built from two separate crystals rather than one could lead to more advanced measurements of quantum effects, including in gravitational fields. Developed by ...

Light changes matter in ways that shape our world. Photons trigger changes in proteins in the eye to enable vision; sunlight splits water into hydrogen and oxygen and creates chemicals through ...
