TL;DR

This paper explores transformation optics to develop advanced cloaking and illusion devices, enabling arbitrary object appearances and discussing superlenses within the transformation optics framework.

Contribution

It generalizes invisibility cloaking by transforming inhomogeneous structures to produce arbitrary object appearances, expanding the capabilities of transformation optics.

Findings

Generalized cloaking for arbitrary object appearance

Discussion of superlenses as illusion devices

Framework for transformation optics-based illusions

Abstract

In this paper, transformation optics is presented together with a generalization of invisibility cloaking: instead of an empty region of space, an inhomogeneous structure is transformed via Pendry's map in order to give, to any object hidden in the central hole of the cloak, a completely arbitrary appearance. Other illusion devices based on superlenses considered from the point of view of transformation optics are also discussed.
