Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
