TL;DR
This paper explores how zero index metamaterials can be engineered to achieve super-reflection and cloaking effects, enabling control over wave propagation and object concealment based on their intrinsic properties.
Contribution
It introduces novel configurations of zero index metamaterials with perfect conductors for super-reflection and cloaking, expanding the functional capabilities of metamaterials.
Findings
Zero index metamaterials can block or conceal objects effectively.
Configurations depend on the type of perfect conductor inclusion.
The physics is governed by the intrinsic properties of ZIM.
Abstract
A zero index metamaterial (ZIM) can be utilized to block wave (super-reflection) or conceal objects completely (cloaking). The "super-reflection" device is realized by a ZIM with a perfect electric (magnetic) conductor inclusion of arbitrary shape and size for a transverse electric (magnetic) incident wave. In contrast, a ZIM with a perfect magnetic (electric) conductor inclusion for a transverse electric (magnetic) incident wave can be used to conceal objects of arbitrary shape. The underlying physics here is determined by the intrinsic properties of the ZIM.
