Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a ...

A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure hologram platform that operates solely based on the wavelength of light and ...

ABSTRACT: This study addresses the limitations of conventional metasurfaces, which exhibit symmetric electromagnetic responses under forward and backward incidences and are difficult to achieve ...

A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial location functioning as an encryption key. (Nanowerk Spotlight) Most storage ...

Have you ever found yourself operating on autopilot? Maybe you’ve driven home from work and don’t remember much about the drive. Or maybe you realize, suddenly, that you’ve been scrolling social media ...

Columbia Engineering researchers have taken another step toward shrinking quantum hardware. The team has created an ultrathin metasurface device that boosts nonlinear optical effects at the nanoscale.

Photoshop CS6 tutorial showing how to add a realistic, rippling, water reflection to a photo. The reflection will ripple out from its center as if you dropped a pebble into a lake or pond. John ...

Hi, I try to build geometric paramters -phase library for reflection metasurface. How should I setup the relative location of source, meta-atoms, and monitors? And the phase is calculated by S11?

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

The big fund-raising round was the latest sign of investor fervor for artificial intelligence companies despite concerns that the boom is overheated. By Michael J. de la Merced For much of the past ...
