Researchers at the Universitat Autonoma de Barcelona have recently designed a peculiar material — called a dc metamaterial — that has the property of making objects wrapped in it undetectable to magnetic and very low-frequency electromagnetic fields. The breakthrough brings the dream of "invisibility cloaking" closer to reality and could have important repercussions in both the military and medical fields.
