Negative refraction and Negative refractive index
... angle of the wave vector exceeds the incident angle and a critical angle ( θc = sin −1 (s x N eff / N 0 ) ) can be defined as the refracted angle of the wave vector reaches 90° . When the incident angle exceeds the critical angle, total reflection does not occur, but the index of refraction becomes ...

... Light propagation through disordered media is often treated as a statistical process in which photons diffuse in a random fashion. The wave nature of the light is clearly manifested, however, if it stays coherent during propagation and the structural variations of the medium are negligible over the ...
