In Friday’s issue of Science, a team of scientists have succeeded in hiding a copper cylinder from microwaves.
In contrast to stealth technology that reduces the cross-section of an aircraft that is visible to radar, cloaking technology passes the radar and other wave around the object — giving the impression to a viewer that it isn’t there.
The cloak designer David Schurig, a research associate at Duke Universityâ€™s electrical and computer engineering department, believes that he can adapt his microwave cloaking success to cloaking visible light waves. His work involves “metamaterials,” blends of polymers and tiny coils or wires that twist the paths of electromagnetic radiation.
This field opens up a whole new category of potential applications such as protecting sensitive electronics from harmful radiation, or perhaps even cloaking an ugly structure that’s blocking your view of the lake.
