A new field of physics has appeared with the emergence of materials known as "Left handed materials" (LHM) or "metamaterials". These materials show very particular characteristics. Their index of refraction has a negative value, which results in the reversal of Snell's law. Whereas, in traditional material the Poynting vector S always forms a right- handed triplet with E and H (S = E Lambda H). In the left handed media, the Poynting vector S and the wave vector K are in opposite directions… CONTINUE READING
