Technology could make it possible to use radio emissions from cell phone networks to wirelessly power sensors and LEDs. Researchers have developed a new metasurface-based…
The elastic material with embedded magnets whose poles are color-coded red and blue. Orienting the magnets in different directions changes the metamaterial’s response. Credit: Courtesy…
New approach expands the application of powerful, ultrafast laser pulses. Quick bursts of laser light, lasting less than a trillionth of a second, are used…
H z component diagram when the point source is placed at r = R1 (a) in vacuum and (b) a-MoO3 invisibility concentrator and r =…
A metasurface made of arsenic trisulfide nanowires (yellow) transmit an incoming near-infrared frequency (red) as well as its third harmonic ultraviolet frequency (violet), which would…
Sound vortex generation enabled by the spin-orbit interaction in real space. Credit: Wang, S., Zhang, G., Wang, X. et al. / DOI number: 10.1038/s41467-021-26375-9 Can…
Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat…
Origami- and kirigami-based metamaterials have applications from robotics to medical devices. The ancient arts of origami, the art of paper-folding, and kirigami, the art of…
Researchers encoded patterns and designs into the material by making tiny, invisible tweaks to the geometry of the triangular lattice. Credit: Image courtesy of Shucong…
Close-up of the new MIT metasurface, or flat optical device patterned with some 100,000 nanoscale structures, that is integrated on a silicon chip and can…
In a proof of concept, researchers created more than a dozen reconfigurable building blocks. Each block consisted of eight connected paper cubes and could be…
Over the past 20 years, scientists have been developing metamaterials, or materials that don’t occur naturally and whose mechanical properties result from their designed structure…
The new metamaterial designed by the researchers. Credit: Coulais et al. Sometimes, the inside of a material can determine what happens on the outside. A…
