Antireflection coatings are familiar from their use in everyday optical devices, such as glasses and lenses. They can increase the amount of light that passes through optical instruments by reducing the fraction of light ...
Metamaterials are engineered to interact with light and sound waves in ways that natural materials cannot. They thus have the potential to be used in exciting new applications, such as invisibility cloaks, high-resolution ...
It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists at Harvard's Wyss Institute ...
Controlling and bending light around an object so it appears invisible to the naked eye is the theory behind fictional invisibility cloaks.
Engineers and scientists have been trying to discover the ultimate "cloaking" device – not just as a hat trick to make things invisible—but for its applications in defence technology. Now, a team from the NUS Department ...
(Â鶹ÒùÔº) —University of Cincinnati researchers are discovering how to manipulate light to one day better view the world's tiniest objects through a super-lens, as well as how to hide an object in plain sight.
A Chinese-U.S. research team is exploring the use of metamaterials—artificial materials engineered to have exotic properties not found in nature—to create devices that manipulate sound in versatile and unprecedented ways.
Microsystems are at the heart of portable hearing aids and implants. Now researchers are developing a miniature, low-power wireless microsystem to make these medical aids smaller, more comfortable and more efficient.
The optical properties of a material are predominantly determined by its constituent atoms and electrons and the way that these respond to electromagnetic waves. In natural materials, the diversity of possible optical characteristics ...
Diamonds may be a girl's best friend, but they could also one day help us understand how the brain processes information, thanks to a new sensing technique developed at MIT.
