First Demonstration Of Time Cloaking  - Technology Review

First Demonstration Of Time Cloaking  - Technology Review: Time cloaking is possible because of a kind of duality between space and time in electromagnetic theory. In particular, the diffraction of a beam of light in space is mathematically equivalent to the temporal propagation of light through a dispersive medium. In other words, diffraction and dispersion are symmetric in spacetime.
