Waveguide array transports light without distortion

One of the challenges of optical microscopy is to continually increase the imaging power, or resolution. In the past three hundred odd years, scientists have been building ever-better microscopes. The limit, for a long time, ...

Engineering discovery brings invisibility closer to reality

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, ...

Ultrasounds dance the 'moonwalk' in new metamaterial

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 ...

Researchers peek at the forgotten component of light

(Phys.org) —Physicists from FOM institute AMOLF have for the first time simultaneously measured the electrical and magnetic fields of light. With such a measurement scientists can better understand the behaviour of light ...

Organic chemistry: Leading light waves astray

The development of structured synthetic materials with unusual electromagnetic properties, so-called metamaterials, promises to provide access to special physical effects of great technological interest. Metamaterials have ...

Bending light the 'wrong' way

(PhysOrg.com) -- Scientists have tried this with sophisticated meta-materials, but at the Vienna University of Technology (TU Vienna) it has now been done with simple metals; materials with a negative refractive index bend ...
