An international team of researchers (China, Singapore) used a negative resistor network with active elements 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. The cloak does not require any knowledge of the hidden object. The cloaking device may find potential applications in medical or geologic research…read more. Open Access TECHNICAL ARTICLE
