Uniform Refraction in Negative Refractive Index Materials [PDF]
Journal of the Optical Society of America A, 2015 We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain ...
