Uniform refraction in negative refractive index materials [PDF]

open access: yesJournal 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

RBF-Based Camera Model Based on a Ray Constraint to Compensate for Refraction Error

open access: yesSensors, 2023
A camera equipped with a transparent shield can be modeled using the pinhole camera model and residual error vectors defined by the difference between the estimated ray from the pinhole camera model and the actual three-dimensional (3D) point.
