Negative refraction is a startling phenomenon whereby light is bent the 'wrong way' as it refracts into a medium with negative refractive index. Now these conditions can be realized in metamaterials designed to have the desired properties. The consequences are far reaching and open a Pandora's box of possibilities in electromagnetism which scientists and engineers are just beginning to explore. The special issue authored by leading authorities covers key concepts in this emerging field.
