Inprentus won a TASA contract to produce diffraction gratings, closely following a recent NASA award, highlighting ...

Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — a positron — locked in orbit ...

Physicists in Japan have, for the first time, observed quantum interference in a beam of positronium — a short-lived atom made of an electron and its antimatter twin, the positron. The experiment ...

Abstract: In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, ...

Abstract: The conventional laser triangulation displacement sensor (LTDS) is difficult to achieve large dynamic range and high precision measurement simultaneously, since LTDS is affected by factors ...

This year’s Met Gala dress code was Fashion is Art – but in nature, you'll find many species that put on their own fashion show.

Metasurfaces and metalenses are advancing high-resolution imaging, providing exceptional light control and improving ...

Chiang Mai’s art scene this May moves from institutional group exhibitions and calligraphy to interdisciplinary projects and independent space programming across the city. Chian ...

This repository is a reproduction of the code of the paper, "All-optical machine learning using diffractive deep neural networks". The calculation method of wave propagation can be found in the ...
