Figure 1. Schematic diagram of the racemic metasurface. (a) Arbitrary polarization-wavefront conversion. (b) Racemic "super-units". Chirality is one of the fundamental phenomena widely present in ...

(Nanowerk News) Dielectric metasurfaces represent one of the cutting-edge research and application directions in the current optical field. They not only possess the advantage of low loss but also ...

Proposed device outlines new paths forward for compact ultra-sensitive optical sensors, multi-band switches with high ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

(Nanowerk News) The expression "flawless from every angle" is commonly used to characterize a celebrity's appearance. This doesn't simply imply that they appear attractive from a specific viewpoint, ...

In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature. Photons are ...

Conventionally, active metasurface scientists have mainly concentrated on altering the dielectric constant and permeability of the substrate, which usually leads to resonance effect and ohmic loss.

Stranger Things fans will be familiar with this scene: Eleven, a girl with telekinetic powers, stares intently at a Coke can. Without physically touching the can, she completely crushes it using her ...
