Multivariate Techniques for Identifying Diffractive Interactions at the LHC [PDF]
, 2009 Close to one half of the LHC events are expected to be due to elastic or inelastic diffractive scattering. Still, predictions based on extrapolations of experimental data at lower energies differ by large factors in estimating the relative rate of ...

Shapeshifting Diffractive Optical Devices [PDF]
Laser & Photonics Reviews, 2022 AbstractIn optical devices like diffraction gratings and Fresnel lenses, light wavefront is engineered through the structuring of device surface morphology, within thicknesses comparable to the light wavelength. Fabrication of such diffractive optical elements involves highly accurate multistep lithographic processes that in fact set into stone both ...
