LLNL scientist wins best poster presentation award at IAEA
A
presentation on developing advanced radio frequency identification (RFID)
systems by an LLNL electronics engineer won the best poster award in a
technical session at a recent International Atomic Energy Agency (IAEA)
symposium held in Vienna.
The presentation by Faranak Nekoogar, "Advanced Radio Frequency Tags for Safeguards Applications," was one of the 15 concepts that were accepted and presented in the IAEA's "Advancements in Containment and Surveillance" session.
The Livermore technology permits detection, remote monitoring and tracking of cylinders with nuclear materials and provides a substantial monitoring improvement at various stages of the enrichment process.
No currently available commercial RFID system can address the IAEA requirements for radio frequency tagging and tracking of nuclear material containers, according to Nekoogar, who works in the National Security Engineering Division.
"We are pleased that this technology -- ultra-wideband (UWB) RFID -- is moving forward in gaining acceptance by the IAEA community," Nekoogar said.
The ultra-wideband communications system for reading tags on nuclear materials offers a number of advantages over narrow band communication systems according to Nekoogar.
One fundamental advantage involves the resilience of the extremely narrow UWB pulses with respect to signal fading. Yet another significant advantage of the LLNL RF tag is that it operates without batteries, so that the tag is remotely charged by ultra-wideband pulses. As envisioned, the RFID tags can be attached to metallic cylinders used in various arms control and safeguards applications.
"Each tag has a unique identity and can be read from at least 100 feet. If necessary, the signal can be relayed to a satellite or a wireless network hundreds or thousands of miles away," Nekoogar said.
Besides the use of UWB systems in safeguards and arms control, Nekoogar sees applications for communications in ships, inside buildings, and underground structures.
The Livermore RFID system has been under development by Nekoogar and her team, LLNL electronics engineers Farid Dowla and Dave Benzel, and a number of academic and industrial partners, for the past few years. This research has been supported by the Department of Energy's Office of Dismantlement and Transparency and the Non-proliferation Research & Development Global Safeguards Program.
Nekoogar joined LLNL from Silicon Valley industry in 2003 as she was completing her Ph.D. dissertation on "UWB Communications for Harsh Environments."
Since joining the Laboratory, Nekoogar has filed more than 20 patents and authored three books -- " From ASICS to SOCs -- A Practical Approach" (2003), "Ultra-wideband Communications -- Fundamentals and Applications" (2005), and "Ultra-wideband Radio Frequency Identification Systems" (2011), which was written with Dowla of LLNL.
