Hiding Under the Carpet: a New Strategy for Cloaking

TL;DR

This paper introduces a novel cloaking strategy that renders objects as flat conducting sheets, avoiding singular parameters and enabling broadband optical cloaking with isotropic materials.

Contribution

It proposes a new cloaking method that simplifies material requirements and enhances broadband optical cloaking capabilities.

Findings

Cloak makes objects appear as flat conducting sheets.

Parameters of the cloak are non-singular and isotropic.

Advances broadband cloaking in optical frequencies.

Abstract

A new type of cloak is discussed: one that gives all cloaked objects the appearance of a flat conducting sheet. It has the advantage that none of the parameters of the cloak is singular and can in fact be made isotropic. It makes broadband cloaking in the optical frequencies one step closer.
