Absolute instruments and perfect imaging in geometrical optics
Tomas Tyc, Lenka Herzanova, Martin Sarbort +1
We investigate imaging by spherically symmetric absolute instruments that provide perfect imaging in the sense of geometrical optics. We derive a number of properties of such devic…
Invisibility cloaking without superluminal propagation
Janos Perczel, Tomas Tyc, Ulf Leonhardt
Conventional cloaking based on Euclidean transformation optics requires that the speed of light should tend to infinity on the inner surface of the cloak. Non-Euclidean cloaking st…
Magnifying absolute instruments for optically homogeneous regions
Tomas Tyc
We propose a class of magnifying absolute optical instruments with a positive isotropic refractive index. They create magnified stigmatic images, either virtual or real, of optical…
Conformal cloak for waves
Huanyang Chen, Ulf Leonhardt, Tomas Tyc
Conformal invisibility devices are only supposed to work within the validity range of geometrical optics. Here we show by numerical simulations and analytical arguments that for ce…
