Introducing the non-radiating antenna

An international team of physicists has created what might seem like a contradiction in terms: a non-radiating source of electromagnetism. By placing antennas inside a hollow dielectric disc, the researchers exploited interference phenomena to create a non-radiative “meta-atom” that could have applications in several areas, including sensing and wireless power transfer.
