Abstract

The search for perfection So-called left-handed materials were first raised as a possibility by Russian theorist Victor Veselago. Engineered for negative permeability and permittivity, their effect on electromagnetic radiation would be the exact opposite to that of natural materials. More recently, it was realized that left-handed materials might be used to make a perfect lens, capable of focusing light much more narrowly than conventional optics. Materials of this type have now been synthesized, but so far the phenomenon has been restricted to microwave wavelengths. Now Grigorenko et al. demonstrate the feasibility of left-handed materials for visible light. To extend the frequency range of magnetic response by three orders of magnitude required a very different design for the new material, entering the area of ‘plasmon optics’. So the groundwork for a ‘perfect lens’ suitable for optical microscopes may now be in place, although considerable technical challenges lie ahead.
