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 uniform refraction property, both in the near and far field cases. In the near field problem, unlike

Terahertz Computed Tomography of High-Refractive-Index Objects Based on Refractive Index Matching
IEEE Photonics Journal, 2018 Terahertz (THz) computed tomography (CT) is a promising technique to obtain the internal information of objects due to its properties of nonionizing and high penetration of nonpolar objects. However, THz CT is hindered by the strong refractive effect and

Quantum storage via refractive index control [PDF]
, 2011 Off-resonant Raman interaction of a single-photon wave packet and a classical control field in an atomic medium with controlled refractive index is investigated. It is shown that a continuous change of refractive index during the interaction leads to the

Mechanisms of femtosecond laser-induced refractive index modification of poly(methyl methacrylate) [PDF]
, 2010 The mechanisms of refractive index change in poly(methyl methacrylate) by frequency doubled femtosecond laser pulses are investigated. It is demonstrated that positive refractive index modificaton can be caused by a combination of depolymerization and ...
