Negative refraction: Negative phase velocity, Electromagnetic interactions & Refraction

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…
