Space–time Symmetry Renders Optical Systems Invisible

For the first time ever, physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in proving that an optical system can be ‘invisible' from one side and act like a mirror from the other side. The study has been published in Nature.

Metamaterial for Optical Advances

Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar cells. moreFeb. 06, 2012

Near-Field Microscopy with Superlenses

Conventional imaging devices are limited in their resolution and, hence, restrict the insights into structures smaller than the wavelength. Near-field microscopy overcomes this limitation by probing evanescent fields resulting in a wavelength-independent resolution. A superlens is a planar device, which transforms these fields to an image plane. We study such lenses for the infrared based on perovskite oxides, which might be applicable to imaging of highly-damped samples e.g. in liquids. moreJan. 23, 2012

Creation of Superlenses - A Scientific Challenge

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones.
