BEDFORD, Mass.--(BUSINESS WIRE)--Fractal Antenna Systems, Inc. today received US patent 9,482,474, entitled “Radiative Transfer and Power Control with Fractal Metamaterial and Plasmonics”. The patent divulges a fundamental new approach to power gathering and transport, as well as heat transfer, with the innovation of metamaterials based on fractal geometry.

“Radiative Transfer and Power Control with Fractal Metamaterial and Plasmonics”

Fractal metamaterials are collections of detached resonators, themselves intricate structures made from repeated and scaled designs. Each fractal resonator lies close to another, collecting and transferring its energy along with adjacent ones, without actual physical connection. The process happens at the speed of light and is a man-made form of ‘radiative transfer’. Fractals afford highly efficient and tighter packing that uniquely achieves the effect, with multiple band and broadband performance.

The new patent broadly claims fractal metamaterials and details uses for power and heating/cooling.

Fractal metamaterial may be used to collect, move, and control energy, for example, and can be physically flexible. Moreover fractal metamaterial can be widely tuned to best work at a desired spectrum, and the resonators can be arranged to magnify, via collection, the power gain, with no physical connections. It provides collection and control benefits without wires or lenses, for example.

Much has been reported in recent years about the across-the-board value of fractal metamaterials, including their use in flat lenses, invisibility cloaks, deflector shields, antennas, absorbers, filters, and so on. The new patent enables those embodiments and establishes the firm’s role as holder of the ‘source invention’.

The inventor of fractal metamaterials is the firm’s CEO, Nathan Cohen, who is no novice to innovation. A Ph.D. astrophysicist and retired university professor, Cohen holds dozens of imaging and related patents and is the inventor of fractal antennas, the invisibility cloak, and deflector shield, among others. His broad background has provided unique insight into energy and related processes, leveraging into practical applications.

Fractal metamaterials are ideal for energy harvesting and wireless charging and are likely to be a key enabler in the next generation of solar energy collection. In addition, the patent discloses the ability of fractal metamaterials to dissipate surplus energy away from a hotspot. This allows new forms of lightweight heat sinks, shielding, heat pumps, and refrigerators, with many commercial and defense uses. Cohen believes a new era of power collection and transport, cooling, and heating technologies will emerge in the next few years from the invention, in addition to imaging related and other uses.
