U.S. National Committee for URSI

The National Academy of Sciences is the U.S. adhering body of the International Union for Radio Science (URSI), and NAS manages the relationship with URSI through the U.S. National Committee (USNC) for URSI. URSI is a non-governmental and non-profit organization under the International Council for Science, responsible for stimulating and coordinating, on an international basis, studies, research, applications, scientific exchange, and communication in the fields of radio science. 


2016 USNC/URSI Meeting: January 6-9
The next annual USNC/URSI meeting will be held from Wednesday, January 6 through Saturday, January 9 in Boulder, Colorado. Graduate students who have submitted abstracts for the Ernest K. Smith USNC/URSI Paper Competition should expect to be notified of acceptance by November 2015. Full papers up to 25 pages are eligible for prizes: First place in the amount of $1000, second place at $750, and third place at $500. Participants may also elect to submit their full papers for publication in the journal Radio Science. For more conference details, including topics and contact information, click here.


2015 IEEE AP-S Symposium on Antennas and Propagation and URSI USNC/CNC Joint Meeting
The 2015 IEEE AP-S Symposium on Antennas and Propagation and URSI USNC/CNC Joint Meeting was held July 19-25, 2015 in Vancouver, Canada. ´╗┐This event also served as the meeting time for the USNC/URSI. The symposium and meeting were sponsored by the IEEE Antennas and Propagation Society (AP-S) and the U.S. and Canadian national committees (USNC/CNC) of URSI. The technical sessions, workshops, and short courses were coordinated between these groups to provide a comprehensive and well-balanced program. For more details, please consult the Joint Meeting website

To assist with travel costs, the USNC/URSI awarded 72 travel fellowship grants to North American students attending the symposium.

The winners of the NARSM Student Paper Competition were:

  • 1st Place -- Luz Maria Neira, "Investigation of High Resolution Microwave Breast Imaging Using a 3-D Inverse Scattering Algorithm with a Variable-Strength Spatial Prior Constraints"
  • 2nd Place -- Jeffrey S. Jensen, "A Cognitive Spatial Learning Control System For 3-Dimensional Random Arrays"
  • 3rd Place (Tie) -- Jonathan M. Pozderac, "X-Band Beacon-Receiver Array Evaporation Duct Height Estimation," and
    Seyed Mohamad Amin Momeni Hasan Abadi, "Wideband Polarization Converters Based on Miniaturized-Element Frequency Selective Surfaces

First URSI Atlantic Radio Science Conference
The first URSI Atlantic Radio Science Conference (URSI AT-RASC) was held in Gran Canaria, Spain, May 18-22, 2015. Finalists presented their research at the 4th International URSI Student Paper Prize Competition, where awards of $750, $500, and $250 were given to the 1st, 2nd, and 3rd place winners, respectively. This conference is part of a new URSI initiative to encourage increased technical activities in all ten URSI Commissions in the years between the General Assemblies and Scientific Symposia. For more details, please visit the URSI AT-RASC website.                                                                                           

31st URSI General Assembly and Scientific Symposium: August 16-23, 2014
The 31st URSI General Assembly and Scientific Symposium (GASS) was held August 16-23, 2014 in Beijing, China. The U.S. Delegation to the GASS included Steven C. Reising and Yahya Rahmat-Samii.

The GASS had a scientific program organized around the ten Commissions of URSI, including oral sessions, poster sessions, plenary and public lectures, and tutorials. In addition, there were workshops, short courses, special programs for Young Scientists, a student paper competition, programs for accompanying persons, and industrial exhibits. For more details, please visit the XXXI URSI General Assembly website.

In collaboration with the Union, the USNC/URSI administered three international awards at the 2014 URSI GASS: the 2014 Dellinger Medal, awarded to J.P.G. Berenger (France); the Booker Award, given to H.V Poor (U.S.); and the Booker Fellowship, awarded to Mona Jarrahi (U.S.). A new URSI prize was also created in honor of Professor Santimay Basu, which rewards a prominent early career in the field. This new prize is administered by the USNC/URSI and was awarded as part of the 2014 URSI GASS. The first awardee was Morris B. Cohen from Georgia Tech. 

Election results from the 2014 GASS included the following winning candidates from the U.S.:
  • URSI Vice-President Elections: Umran Inan (Stanford University)
  • Commission Vice-Chair Elections: Amir Zaghloul (Commission C), V. Chandrasekar (Commission F), Patricia Doherty (Commission G), and Richard Bradley (Commission J)
  • Commission Early Career Representative Elections: Seebany Datta-Barua (Commission G) and Wen Li (Commission H)
The URSI Student Paper Competition has been held at URSI General Assembly and Scientific Symposiums (URSI GASS) since 2008. Finalists are judged on both the content and delivery of their talks. Certificates and monetary prizes, provided by the USNC-URSI, are awarded. The 2014 winners were:
  • First Prize Winner: Filipa Prudêncio (University of Lisbon, Portugal)
  • Second Prize Winner: Simon Adrian (Télécom Bretagne, France and the Technische Universität München, Munich, Germany)
  • Third Prize Winner: Andreas Ericsson (Lund University, Sweden)
  • Fourth Prize Winner: Jiangfeng Wu (University of Michigan)
  • Fifth Prize Winner: Sean Elvidge (University of Birmingham, United Kingdom)

2014 IEEE AP-S and USNC/URSI Radio Science Meeting: July 6-11, 2014
The 2014 IEEE International Symposium on Antennas and Propagation and USNC/URSI Radio Science Meeting was held jointly July 6–11, 2014 in Memphis, TN. The symposium and meeting were co-sponsored by the IEEE Antennas and Propagation Society (AP-S) and the USNC/URSI Commissions A, B, C, D, E, F, G, and K. The joint meeting was intended to provide an international forum for the exchange of information on state-of-the-art research in antennas, propagation, electromagnetics, and radio science. For more information, please visit the meeting website.

National Radio Science Meeting: January 8-11, 2014
This open scientific meeting was sponsored by the U.S. National Committee (USNC) of the International Union of Radio Science (URSI). Through technical co-sponsorship of the meeting by the IEEE Antennas and Propagation Society, the authors of abstracts that were presented at the meeting had the option of archiving their abstracts by having them be submitted to IEEE Xplore. 

The Ernest K. Smith Student Paper Competition is organized at each National Radio Science Meeting. Papers are reviewed by representatives of the 10 USNC-URSI commissions and the top three authors are invited to present their research at a special plenary session. The 2014 winners were:

First Prize: Simulating Hypervelocity Impact Plasmas and their Effects on Spacecraft (Commission H)
