Engineers at the UCLA Samueli School of Engineering have introduced a universal framework for point spread function (PSF) engineering, enabling the synthesis of arbitrary, spatially varying 3D PSFs ...

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 ...

Audeze, the renowned premium headphone manufacturer trusted by professionals worldwide, has officially introduced the LCD-S20, a closed-back planar magnetic headphone priced at just $499. This launch ...

Recently, diffraction elements that reverse the color sequence normally observed in planar diffraction gratings have been ... of the hierarchical nature of the superposed, orthogonal grating features.

Abstract: Planar grating diffraction analysis based on Legendre expansion of electromagnetic fields is reported. In contrast to conventional RCWA in which the solution is obtained using state ...

we have reviewed the research progress for planar optics-based glass-free 3D displays: diffraction grating-based, diffractive lens-based and metasurface-based. Compared with geometric optics-based 3D ...

An SOI micro-spectrometer was built using a circular diffraction grating containing an elliptical ... A silicon-on-insulator (SOI) planar waveguide compatible with CMOS manufacturing technique ...

One of the most desirable functions of a diffraction grating is its ability to scatter incident light ... a recently emerged approach is to use planar metagratings comprised of designer multiresonant ...
