"Cloaking technology could be used to make obstacles that impede communications signals 'disappear,'" said David Smith of Duke University in North Carolina, who worked on the study published in the journal Science.

Smith was part of the same research team that in 2006 proved such a device was possible.

He said the new material is easier to make and has a far greater bandwidth. It is made from a so-called metamaterial -- an engineered, exotic substance with properties not seen in nature.
