An achiral metasurface selectively transmits two beams of opposite chirality. Read More »
An all-dielectric version of a metamaterials-based cavity allows the cavity to operate over a previously inaccessible wavelength range—which could benefit lasers and other resonant devices. Read More »
A simplified model of how yarns interact shows that a piece of knitted fabric can have many stable resting states depending on its history of deformation. Read More »
Using an old film as input, researchers demonstrate an algorithm that rapidly determines the positions of thousands of particles whose light-scattering produces an image or other desired output. Read More »
Novel metamaterial-based architectures offer a promising platform for building mass-producible, reprogrammable schemes that perform computing tasks with light. Read More »
A proposed ring-shaped device could measure the concentration of glucose in a person’s blood to an accuracy sufficient to make it clinically useful. Read More »
The winners of the third annual “Gallery of Soft Matter” competition included posters portraying robotic leaves and cannibalizing droplets and a video with what might be Steamboat Willie’s first appearance at the APS March Meeting. Read More »
A lightweight structure made of rubber and metal layers can provide an object with underwater acoustic stealth over a broad frequency range. Read More »
A water wave incident on a grooved wall is shown to be analogous to electromagnetic waves called surface plasmon polaritons. Read More »
A new technique creates defects in a topological acoustic system that don’t destroy the system's chiral symmetry, protecting its topological states. Read More »
