  Nathan Cohen, left, founder of Fractal Antenna, and company CEO David Moschella scored an exclusive licensing deal last week with Nashua Corp., which has agreed to manufacture and distribute passive RFID labels and tags using antennas developed by Fractal.
  ...
  Nathan "Chip" Cohen founded Fractal Antenna Systems Inc. in the classic startup way: tinkering in his basement while working a day job.
  
  In 1987 Cohen was a Boston University astronomy professor when he attended a conference where Benoit Mandelbrot, the famed founder of fractal geometry, was speaking.Cohen was inspired by his lecture on fractals -- geometric shapes that can be subdivided into parts, each of which looks like the whole.

  "By working with Nashua Corp. to incorporate fractal antenna technology into label and tag form factors of all shapes and sizes, we can deliver more accurate and more flexible solutions to the RFID market," said Dr. Nathan Cohen, founder and chief technology officer, Fractal Antenna."Fractal antenna technology is used to deliver similar improvements across many industries including in-building wireless, telematics, electronic warfare and signal intelligence."

  Noted Fractal's CEO Nathan Cohen: "Previous researchers had measured this 'through to the other side' cloaking at a narrow microwave frequency band. Ours is better than ten times wider. By analogy, if this was visible light, the entire spectrum of visible light would easily pass through, not just one color. To our eyes, the cloaked object would not exist."
  
  Wideband behavior has been the main obstacle to making metamaterials, of which cloaks are just one application, truly practical. Cohen believes that many metamaterial applications are now rendered practical from a scientific standpoint, and the remaining challenges are predominantly those of manufacturability, cost, and identifying useful applications. Cohen adds: "We will be using our proprietary wideband metamaterial technology to have some fun with cloaking, but don't expect to cloak Harry Potter soon.

  "Previously antennas had attributes in many form factor and performance regimes, but these new antennas are unprecedented", notes inventor Nathan Cohen, CEO of the firm.
  ...
  "You just can't optimize nor render practical this new class of antennas without fractals and our technology", added Cohen," as the smaller size and pleasing bandwidth attributes of fractal resonators enable the new metamaterial advantages". Cohen also points out that: "The technology has also led to fractal-based arrays that are far smaller than expected from their gain, while maintaining very broadband ability."
  
  The new antenna technology builds on the foundations of the metamaterial physics of plasmonics, first applied by Nobel Prize Winner Gugliemo Marconi in a 1919 patent, and also seen in an obscure type of antenna called a CCD, invented in 1961. "These historical technologies hinted at something beyond their own hoary possibilities, but sometimes it takes a new twist to open up a field. We use fractals in plasmonics to get the currents to be slowly varying across the entire aperture within a wideband, dropping off at the physical boundary conditions. FRACTAL's team had the know-how to be there first and has been working on developing the technology for sometime", noted Cohen.
  ...
  The effect is transformational" said Cohen. The cloak approach applies to most types of conventional antennas, such as patches and slots, as other examples.
  
  The firm first publicly showed the new technology in a live demo at a colloquium at Harvard University in April. Many dozens of scientists; engineers; government researchers; patent attorneys; students; and antenna experts have witnessed the demo.
  
  "Metacloak antennas and their array applications are far and away the most important applied applications of metamaterials to date, taking that field out of the science fiction and research stage and well into applied reality", asserted Cohen.
  
  Cohen believes that the new metacloak antennas leapfrog developments being pursued by other researchers, by 5 to 15 years. "It's common for us to be far ahead of the pack, and we always have a lineup of new technology to roll out", he added.

  Dr. Nathan Cohen, a physicist, radio astronomer, and retired Boston University professor, discovered in 1988 that fractals possess useful antenna element characteristics.Cohen is the Chief Technology Officer of Fractal Antenna Systems, Inc. As described by the Tampere University of Technology researchers, their work demonstrates the advantage of fractal antennas as valuable means of making better performing antennas, especially in the growing RFID marketplace.Such findings were first reported starting in 1995 by Fractal Antenna Systems scientists. The independent research conducted by the Tampere University team while completely impartial and not associated with Fractal Antenna Systems , provides significant validation of the advantage of fractal techniques for antenna miniaturization and performance, said Dr. Cohen.

  Fractal Antenna Systems was founded by Dr. Nathan Cohen, and supplies products for the worlds most demanding wireless applications.

  Fractal Antenna Systems, Inc. was founded in 1995 by Nathan Cohen, now a recently retired Boston University telecommunications professor and radio astronomer.The firm has grown exponentially in the last year, with the continued acceptance of fractal antennas in engineering circles.
  ...
  Notes CTO Nathan Cohen: "We would judge that our knowledge base and development base is at least a decade ahead of what academic researchers are reporting.In fact, we have yet to see anything scientifically substantive that expands upon what we've done many years ago."Cohen further noted that this years-ahead experience translates directly into valuable designs for the company's customers.

  Well-known in graphic design and art, the use of fractals, in antennas, was pioneered over the last 20 years by the firm's Founder and Chief Technical Officer (CTO), Dr. Nathan Cohen.A radio astrophysicist and retired university professor, Cohen concurrently invented tuned electronic circuits using fractals, also called fractal "resonators" and filed patent for them in 1995.
  ...
  "Fractal tuned circuits have become a hotbed for progress in electronic design," added Cohen.
  
  Pointing out the firm's great patience in awaiting the issuance of the important patent, the firm's CEO David Moschella notes that the recognition defines the starting point of the approach and signals the shift of acceptance from a research discipline to one that is applied and market-driven."The researchers have piqued the interest of the electronics industry, and with the patent basis now firmly established it's time to get the applications fielded," said Moschella, in describing the business of the fractal resonator technology to be built on in-house products, as well as licensing.
