“Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. A research paper published in a New Journal of Physics' focus issue 'Cloaking and Transformation Optics' called 'The Transmutation of Singularities in Optical Instruments', written by Thomas Tyc, Masaryk University, and Ulf Leonhardt, the University of St. Andrews and Singapore National University, shows that it is possible to reflect light from all directions.” source...
