Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this ubiquitous energy.
A team of scientists from the Moscow Institute of Â鶹ÒùÔºics and Technology (MIPT) and the Landau Institute for Theoretical Â鶹ÒùÔºics at the Russian Academy of Sciences has proposed a two-dimensional metamaterial composed of silver ...
A team of physicists from ITMO University, Ioffe Â鶹ÒùÔºical-Technical Institute and Australian National University have researched the phenomenon of phase transition between photonic crystals and metamaterials - two types of ...
A single drop of blood is teeming with microorganisms—imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a "perfect lens." The lens hasn't ...
For centuries, artists mixed silver and gold powder with glass to fabricate colorful windows to decorate buildings. The results were impressive, but they didn't have a scientific reason for how these ingredients together ...
A research team has realized one of the long-standing theoretical predictions in nonlinear optical metamaterials: creation of a nonlinear material that has opposite refractive indices at the fundamental and harmonic frequencies ...
Metamaterials - artificial nanostructures engineered with electromagnetic properties not found in nature - offer tantalizing future prospects such as high resolution optical microscopes and superfast optical computers. To ...
Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, ...
(Â鶹ÒùÔº)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...
Metamaterials have extraordinary properties when it comes to diverting and controlling waves, especially sound and light: for instance, they can make an object invisible, or increase the resolving power of a lens. Now, researchers ...
