Closed loop light ray trajectories in transformation optic devices
To completely hide an object within a transformation optics (TO) cloak, a light ray may not leave the cloaked area. A possible realisation of this uses closed-loop light ray trajectories to trap the rays w...

Lighting Design Using Ray Tracing
This article describes lighting system design using ray tracing. This method can be applied in cases where calculation includes non-diffuse reflective materials, light sources have dimensions comparable to distances from re...

Generalized laws of refraction that can lead to wave-optically forbidden light-ray field
on the fact that scalar wave optics allows only certain light-ray fields, we divide through any allowed light-ray field, the laws in the first category always result ina cross section through an allowed light<...

Experimental demonstration of ray-rotation sheets
, the direction of light rays by an arbitrary, but fixed, angle around the sheet normal. These ray-rotation sheets comprise two pairs of confocal lenticular arrays. In addition to rotating the direction of transmitted l...
