Recently, artificially constructed metamaterials have become of considerable interest,
because these materials can exhibit electromagnetic characteristics unlike those of any …

The imaging resolution of conventional lenses is limited by diffraction. Artificially engineered
metamaterials now offer the possibility of building a superlens that overcomes this limit. We …

Using the freedom of design that metamaterials provide, we show how electromagnetic
fields can be redirected at will and propose a design strategy. The conserved fields—electric …

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art
semiconductor nanofabrication process, have realized various novel optical properties. This …

Complex and interesting electromagnetic behavior can be found in spaces with non-flat
topology. When considering the properties of an electromagnetic medium under an arbitrary …

Victor Veselago, in a paper 1 published in 1968, pondered the consequences for
electromagnetic waves interacting with a hypothetical material for which both the electric …

The propagation of light in dispersive media is a subject of fundamental as well as practical
importance. In recent years attention has focused in particular on how refractive index can …
