Fractal’s new patent to expand invisibility cloak and metamaterial scope

December 17, 2014

Fractal Antenna Systems, Inc. announced it has received a second patent notice of allowance (NOA) on invisibility cloaks. Upon issuance the new patent will secure rights on methods to make cloaks, fractal resonator (metamaterial) systems and cloaks of different shapes, among other claims. The new patent will further expand the firm’s pioneering and proprietary position in the emerging and fascinating world of making things disappear.

The firm pioneered the fractal metamaterial that makes invisibility cloaks possible and its patented fractal metamaterial has been an integral part of customers’ products for 5 years, producing novel antenna systems for aerospace, M2M, and in-house cell phone boosters, among others.

Fractal’s new patent will build on awarded patent 8,253,639, the invention of the invisibility cloak--the world’s first--by CEO Nathan Cohen. That was followed with the world’s first cloaking of a person; the first invisible man. Since then the firm has continued its "years ahead" development on cloaking technology and fractal metamaterials, published its results, and has given demonstrations to thousands at engineering meetings and conferences. Notes Cohen, “There is a lot more ahead on the invisibility cloak front. And as usual, seeing, or rather not seeing at all, is believing.”
