Researchers have developed a new type of hologram, known as "metaholograms," capable of projecting multiple high-fidelity ...

Depending on the azimuthal angle and polarization state of guided incident light, the metahologram can selectively project ...

A new method to combat the degradation of the radial focusing ability of near-field beams in the broadside of circular arrays ...

New "metaholograms" could transform AR/VR technologies by enabling crosstalk-free, high-fidelity image projection with vastly ...

A new study published in Nature, conducted by an international collaboration team led by Prof. Wei Li from the Changchun ...

The square symbolized earth and the circular disc symbolized heaven. Upon these were inscribed the azimuthal points relating to the constellations. Its primary use was that of geomancy ...

azimuthal gamma ray, real-time continuous inclination and azimuth, rotary steerable, pressure-while-drilling, mode shifting, stick-slip and destructive dynamics, dynamic sequencing and real-time ...

This study captured deciduous broadleaf BSDFs from the visible through shortwave infrared spectral regions, accurately modeled the BSDF for extension to any illumination angle, viewing zenith or ...
