The refractive index of a material defines the angle through which light is bent when it travels between a material and the vacuum. Ordinary materials such as glass have refractive indices between one ...
In the past decade we have seen the convergence of refractive surgery with cataract surgery, which makes sense because the most commonly performed refractive procedure is phacoemulsification with IOL ...
Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...
