Science closing in on cloak of invisibility

Researchers at Duke University, who developed a material that can “cloak” an item from detection by microwaves, report that they have expanded the number of wavelengths they can block.

“The new device can cloak a much wider spectrum of waves—nearly limitless—and will scale far more easily to infrared and visible light. The approach we used should help us expand and improve our abilities to cloak different types of waves,” senior
researcher David R. Smith said in a statement.

The new cloak  is made up of more than 10,000 individual pieces of fiberglass arranged  in parallel rows. The mathematical formulas are used to determine the  shape and placement of each piece to deflect the electromagnetic waves.- [source]
