Generalized Cloaking and Optical Polyjuice

TL;DR

This paper introduces a generalized cloaking method that transforms an inhomogeneous structure to give any hidden object an arbitrary appearance, expanding the capabilities of traditional cloaking techniques.

Contribution

It presents a novel generalization of cloaking by transforming inhomogeneous structures to control the appearance of hidden objects.

Findings

Enables arbitrary appearance of hidden objects

Extends cloaking to inhomogeneous structures

Uses Pendry's map for transformation

Abstract

In this paper, a generalization of cloaking is presented: 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.
