Fractal Antenna Systems, Inc. disclosed a patent filing for a novel approach to better wireless antennas. Called ‘Fractal Plasmonic Surfaces’ (FPS), the new antenna technology promises to provide wideband ability at low cost along with other unique features. The technology exploits the use of fractals, intricate geometric figures made from scaling and applying a simple pattern. The fractals are placed closely making a doily-like surface layer in a unique antenna me- thod. This system is a ‘metamaterial’ with electroma- gnetic attributes unattainable by other means.
Before the FPS invention, antennas were considered devices that were super sensitive to their environ- ment and placement – and isolated to a specific location. With FPS, antenna placement and tuning are minor issues. In addition the gain of the FPS antenna depends solely on the area, and not how separate antennas are attached and ‘phased.’ The FPS approach also boasts that it is contactless and componentless.
Notes inventor Nathan Cohen: “The FPS essentially is one tiny antenna that makes copies of itself across a layer using surface waves that physicists call ‘plas- mons’. There’s no direct connection or feed. Each of these little antennas adds up to make the antenna analogy of a fly’s eye. Covering one has no effect on the others. The problem of hand- smothering the antenna on smartphones, tablets, and other devices now becomes a thing of the past: the antenna has ‘self configured’.

Nanoparticle Ultracapacitor
USPTO: 7,990,679 Inventors: Scott G. Ehrenberg; Liwei Cao Assignee: Dais Analytic Corporation (Odessa, FL)
Abstract Particular aspects provide capacitors, and particu- larly ultracapacitors, including molecules suitable to substantially increase the capacitance of the capaci- tor, and methods for making same, Particular aspects provide ultracapacitors that include nanoparticles optionally coated with molecules, such as polymer electrolytes. Certain aspects provide an energy sto- rage device or capacitor, including at least three layers sealed in a fluid-tight covering, wherein a first layer includes at least one electrolytic polymer mole- cule of positive charge and at least one nanoparticle; a second dielectric layer including at least one insu- lative polymer; a third layer including at least one electrolytic polymer molecule of negative charge and at least one nanoparticle. In certain aspects, the elec- trolytic polymer of the first layer includes at least one high charge density polymer electrolyte of positive charge, and wherein the electrolytic polymer of the third layer includes at least one high charge density polymer electrolyte of negative charge.
The US patent covers the usage of Dais Analytic’s (OTCBB: DLYT) commercial portfolio of Aqua- lyte nano-structured materials to develop a high- performance energy storage system at lower cost compared to current storage technologies. Through a joint testing deal with the University of Florida, Dais has utilized the concepts of the patent to develop a functional energy storage prototype system called ‘NanoCap’, which is a type of ultracapacitor.
