With the help of integrated CMOS technology and electromagnetic design, Princeton researchers have demonstrated a key device that could potentially enable high-speed wireless links at terahertz ...

Researchers created a new optoelectronic device from the combined use of Holographic Metasurfaces (HMs) and OLEDs.

Metasurfaces, as two-dimensional metamaterials, display fascinating ability in electromagnetic (EM) modulation within a sub-wavelength scale, opening up a new way for manipulating the properties of EM ...

Architecture of the proposed compact twisted meta-device for frequency-reconfigurable holography. The meta-device integrates cascaded radiation-type metasurfaces (RA-M) with phase-only metasurfaces (P ...

Scientists unveil metasurface technology, allowing for angle-dependent holograms. The expression "flawless from every angle" is commonly used to characterize a celebrity's appearance. This doesn't ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...

For years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research ...

A new metasurface-based device can produce multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. Its ability to store information that is only ...

(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, ...

Researchers have uncovered hidden potential in metasurfaces and demonstrated optical devices that manipulate light's polarization state with an unprecedented degree of control. The research ...
