摘要

Abstract

Hiding an arbitrary object with a cloak at a distance from an object is of great significance in scientific research

but remains unrealized as a practical device. In this paper

we propose the first experimental realization of a remote cloaking device that makes any object located at a certain distance invisible at direct current (DC) frequency. A negative resistor network with active elements is used to achieve the remote function of the DC cloak. Based on this network

the cloak can remotely generate a hidden region without distorting the currents far from the cloaked region. The experimental results show that any object in the hidden region is invisible to a DC detector. Our cloak does not require any knowledge of the hidden object. The experimental demonstration shows the superiority of this remote cloaking device

which may find potential applications in medical or geologic research.
