Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

Abstract: The rigorous diffraction boundary problem for a semitransparent slotted semi-infinite cone is considered. Slots are periodically cut along its generatrices from the cone tip. The source ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This echelon diffraction grating came ...

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 ...

Inprentus continues to serve critical global customers on 5 continents. Inprentus was founded in 2012 by University of Illinois Physics Professor Peter Abbamonte to commercialize a novel method for ...

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, ...

Hello，from these figures, we know that the angle of incidence is set to 80°, the grating line density is 5000000.0l/m, the diffraction order is -1, the photon energy of the light source is 620eV, that ...

Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...
