Plasmonic materials can uniquely control the electromagnetic spectrum due to nano-scale surface architecture. Recent advances in nanotechnology and materials science and their combined capacity to ...

Imagine trying to wear a left-handed glove on your right hand: It doesn't fit because left and right hands are mirror images that can't be superimposed on each other. This "handedness" is what ...

A team of researchers has encoded multiple holographic images in a metasurface that can be unlocked separately with differently polarized light. Not far from where Edwin Land -- the inventor of the ...

Engineers have developed a way to encode more than one hologram in a single surface with no loss of resolution. A team at Caltech has figured out a way to encode more than one holographic image in a ...

Encoding images in photon correlations Simplified experimental setup (a). A conventional intensity image (b) reveals no information about the object, while a correlation image acquired using an ...

(Nanowerk News) Imagine trying to wear a left-handed glove on your right hand: it doesn’t fit because left and right hands are mirror images that can’t be superimposed on each other. This ‘handedness’ ...

Increasingly, civilization’s information is stored digitally, and that storage is abundant and growing. We don't bother deleting those seven high-definition videos of the ceiling or 20 blurry photos ...
