Functional Prototype Microwave Invisibility Cloak Made

Prototype invisibility cloak versus microwaves has been created Researchers first fired microwaves at a copper cylinder and recorded the electronic shadow it cast. They next showed in contrast that microwaves largely pass around the invisibility cloak as if it weren't there. "There is some reflection, so this isn't perfect, but it is only a prototype," says David Schurig of Duke University.
