TLDR
A universal 2D transformation formula for embedded transformation optics reveals several interesting phenomena and potential applications, and a "cloak" based on a polarization splitter is proposed for the first time.Abstract:
A universal 2D transformation formula for embedded transformation optics is suggested. Linear and nonlinear transformation results using the suggested formula under different conditions reveal several interesting phenomena and potential applications, and designs for various polarization controllers can be achieved based on this idea. For example, an incident Gaussian beam can be transformed into a typical spherical wave, and a “cloak” based on a polarization splitter is proposed for the first time.read more

Hiding under the Carpet: A New Strategy for Cloaking
TL;DR: A new type of cloak is discussed: one that gives all cloaked objects the appearance of a flat conducting sheet that has the advantage that none of the parameters of the cloak is singular and can in fact be made isotropic.

Broadband Ground-Plane Cloak
TL;DR: An experimental realization of a cloak design that conceals a perturbation on a flat conducting plane, under which an object can be hidden, and results indicate that this type of cloak should scale well toward optical wavelengths.
