H z component diagram when the point source is placed at r = R1 (a) in vacuum and (b) α-MoO3 invisibility concentrator and r = R2 in (c) vacuum and (d) α-MoO3 invisibility concentrator, respectively. ...

Metamaterials are carefully engineered materials that possess desirable properties and can be used to manipulate electromagnetic, acoustic, or other types of waves in interesting ways. Some materials ...

This illustration shows the structure of a new device created by Purdue University researchers to overcome a fundamental obstacle in using new metamaterials for radical advances in optical ...

Invisibility has quietly shifted from fantasy to engineering problem, and the most convincing proof is not a shimmering cape but a magnetic cloaking device that makes fields themselves vanish from ...

There’s a well-known story in Plato’s Republic in which a humble shepherd named Gyges finds a magical gold ring that renders whoever wears it invisible. Gyges proceeds to use his newfound power to ...

Pictured is a leafhopper G. serpenta. Lin Wang et al. studied the geometric designs of the surface coatings on leafhopper bodies. Leafhoppers produce brochosomes to coat their body surfaces, which are ...

In “Invisibility,” the professor of physics and optical science Gregory J. Gbur examines the past and future of everyone’s favorite plot device. By Nathaniel Rich When you purchase an independently ...

The idea of an invisibility cloak may sound more like magic than science, but researchers are currently hard at work producing devices that can scatter and bend light in such a way that it creates the ...

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 ...
