Large-scale, white-light, transformation optics using integral imaging

Large-scale transformation optics — supplementary information

All simulations shown in the paper were performed with our custom ray tracer Dr TIM [1, 2] (Fig. 1). With the instructions provided in this section, the reader should be able to run all simulations described in this paper, shown again in Fig. 2. Further information on how to use Dr TIM can be found in the user guide [3]. Dr TIM runs on any computer capable of running Java programs that require ...

Enhancing imaging systems using transformation optics.

We apply the transformation optical technique to modify or improve conventional refractive and gradient index optical imaging devices. In particular, when it is known that a detector will terminate the paths of rays over some surface, more freedom is available in the transformation approach, since the wave behavior over a large portion of the domain becomes unimportant. For the analyzed configu...

Transformation optics using graphene.

Metamaterials and transformation optics play substantial roles in various branches of optical science and engineering by providing schemes to tailor electromagnetic fields into desired spatial patterns. We report a theoretical study showing that by designing and manipulating spatially inhomogeneous, nonuniform conductivity patterns across a flake of graphene, one can have this material as a one...

Transformation optics and subwavelength control of light.

Our intuitive understanding of light has its foundation in the ray approximation and is intimately connected with our vision. As far as our eyes are concerned, light behaves like a stream of particles. We look inside the wavelength and study the properties of plasmonic structures with dimensions of just a few nanometers, where at a tenth or even a hundredth of the wavelength of visible light th...
