Negative refraction
text:
In optics, negative refraction is the electromagnetic phenomenon where light rays become refracted at an interface that is opposite to their more commonly observed positive refractive properties. Negative refraction can be obtained by using a metamaterial which has been designed to achieve a negative value for electric permittivity (ε) and magnetic permeability (μ); in such cases the material can be assigned a negative refractive index. Such materials are sometimes called "double negative" mater
