Metalenses have been used to image microscopic features of tissue and resolve details smaller than a wavelength of light. Now, Harvard researchers have turned the metalens towards space. Researchers ...

(a) A singlet metalens suffers from large barrel distortion. (b) A compound metalens effectively eliminates the barrel distortion. (c, d) Ray-tracing modeling of the (c) singlet and (d) compound ...

Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

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 ...

In recent years, electronics engineers worldwide have been trying to develop new hardware that could further boost the speed ...

Polarimetry plays a key role in wide applications from remote sensing and astronomy to biology and microscopy. Traditional polarimetry systems are equipped with a set of polarizers, waveplates, ...

Researcher have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. (Nanowerk News) Almost a decade ago, ...

A project at Pennsylvania State University (Penn State) has developed a metasurface intended to extract polarimetric imaging data more rapidly and cost effectively than current methods. Described in ...
