Many metamaterials consist of complex metallic wires and other structures that require sophisticated fabrication technology and are difficult to assemble. The unusual optical effects do not ...

Optical metamaterial is an effective approach to exploit the superior photon capture capability. Thus, the perfect absorbers could be achieved by nanoscale resonant plasmonic and metamaterial ...

Sir John Pendry’s lecture showed how engineered materials make sci-fi real, from invisibility cloaks to microscopes revealing ...

"Metamaterials have great potential for application in optical stealth, and we hope that our materials can be used in this regard. Our next step will be to continue to optimize the composition and ...

These inherent constraints in the optical properties of natural materials have driven the development of artificially engineered metamaterials which rely on the phenomenon of negative refraction.

A recent review article published in Engineering delves into the latest research on enhancing chiral optical signals, a topic with significant ...

Practical low-loss metamaterials at optical frequencies may soon be realized thanks to optical parametric amplification that uses backwards propagation of a signal beam in negative-index ...

However, engineers at the University of California San Diego have published their results using a hyperbolic metamaterial composed of silver and silica to drive optical microscopy down to below 40 ...

The optimized printing approach could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and more. DLW is an additive ...
