Stealth aircraft like the F-35 are built to go slower than older aircraft, so it doesn't emit as much of a heat signature.

The material could someday be used in flexible semiconductors, tear-resistant textiles, bioengineering scaffolds, and more.

Speaking to News18.com, IIT Kanpur Director Prof. Manindra Agrawal discusses how the institute's innovations in AI and stealth tech are shaping India's future.

Finally, the Shalaev and Smolyaninov groups have recently demonstrated broadband cloaking in a specially tapered waveguide, which emulates well the metamaterial-based anisotropic cloak and thus ...

Several examples are showcased, including a crossed-grating guided-mode resonance filter (GMRF), parameter retrieval of a metamaterial, an invisible cloak designed by transformation optics (TO), and ...

It is demonstrated that for specific cloaking parameters the scattered field by the antenna ... correspond to a superstrate filled with an ∊-near-zero or a low-index metamaterial. Finally, the ...

Engineers have fabricated a metamaterial that is not only strong but also stretchy. Their new method could enable stretchable ceramics, glass, and metals, for tear-proof textiles or stretchy ...
