"Invisibility Cloak: Metamaterial Chimera Vanishes Across Visible Light, Microwave, and Infrared"

Originally Published 1 year ago — by Phys.org

A team of engineers in China has developed a metamaterial, called a metamaterial chimera, that is nearly undetectable across visible light, microwave, and infrared spectra. Inspired by the chameleon, glass frog, and bearded dragon, the material reflects electromagnetic waves in ways that mimic these animals' abilities to blend into their surroundings, hide from predators, and remain transparent. The researchers used a five-step process to layer the material, each with its own invisibility characteristics, and found that it worked well in tests, potentially offering applications in wildlife studies and military uses.

"MIT Researchers Push Boundaries with Creative Thinking"

Originally Published 2 years ago — by MIT News

Mathias Kolle, an associate professor of mechanical engineering at MIT, is studying the microstructure of butterfly wings and other optically interesting organisms to replicate and improve upon their structural, light-bending effects. Inspired by nature, Kolle and his students are designing materials that exhibit advanced optical functions, including color-changing sheets and fibers that can be integrated into medical bandages or used for strength-testing knots. They aim to create materials that generate colors without chemicals, using the structure itself to produce brilliant and vibrant colors.
