Using Superconducting Materials to Create Invisibility Devices

Invisibility devices may soon no longer be the stuff of science fiction. A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (a-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel optical devices.

Holography: Origins, Problems, and Possible Solutions

Most people own at least one hologram, probably without knowing it's a hologram. Those with relatively little optical background, most of the general public, are most likely to encounter real holograms, face to face, in museums, magazines, art galleries, holographic displays, and security devices (such as those on credit cards).

New Filter-Free Imaging Sensors Could Improve Low-Light, Fast Imaging

Newly developed pixel-scale metasurface lenses—flat surfaces that modify light using nanostructures—have been demonstrated to help create imaging sensors that are about three times more sensitive than those now in use. The new sensor architecture may allow digital cameras to image faster or in low-light circumstances.
