A New Optical Metamaterial Makes True One-Way Glass Possible

A new approach has allowed researchers at Aalto University to design a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific electromagnetic properties, which means scientists can create materials with features desirable for industrial applications.

Advancements Make Laser-Based Imaging Simpler and Three-Dimensional

There are times when scientific progress comes in the form of discovering something completely new. Other times, progress boils down to doing something better, faster, or more easily. New research from the lab of Caltech’s Lihong Wang, the Bren Professor of Medical Engineering and Electrical Engineering, is the latter. Read on to learn more.

Highest-Resolution Single-Photon Superconducting Camera

The NIST camera is made up of grids of ultrathin electrical wires, cooled to near absolute zero, in which current moves with no resistance until a wire is struck by a photon. In these superconducting-nanowire cameras, the energy imparted by even a single photon can be detected because it shuts down the superconductivity at a particular location (pixel) on the grid. Combining all the locations and intensities of all the photons makes up an image.
