Fractal Antenna Systems, Inc. has received US patent 9,482,474, entitled “Radiative Transfer and Power Control with Fractal Metamaterial and Plasmonics,” the company said.
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.
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.
