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. 


Travel Fellowships to U.S. Early Careers Participating in GASS 2017, Montreal, Canada
For the thirty-second time since the inception of URSI, Radio Scientists from across the world will get together for the URSI General Assembly and Scientific Symposium on August 19-26, 2017 in Montreal, Canada.  This conference is a unique opportunity to learn about recent advances in all fields of Radio Science, as covered by all ten URSI Commissions. The USNC-URSI will award 30 travel fellowships of $1,000/each to U.S. early careers. For more information on GASS 2017, please visit the site


2017 USNC-URSI Meeting and Student Paper Competition, January 4--7 in Boulder, Colorado
The most recent annual National Radio Science Meeting (NRSM) was held from Wednesday, January 4 through Saturday, January 7 in Boulder, Colorado. The meeting offered Student Travel Grant awards to both graduate and undergraduate students, and featured the 120 Ernest K. Smith Student Paper Competition.

This 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 the Ernest K. Smith Student Competition held during the Plenary event. This year, the top three winners received a prize of $750 each:

Radio-Frequency Emission Detection and Scaling from Hypervelocity Impacts on Charged Targets
(Commission G)
Andrew Nuttall* and Sigrid Close, Department of Aeronautics and Astronautics, Stanford University

Warm Plasma Raytracing of Whistler Mode 2 Waves in the Earth's Magnetosphere
(Comission H)
Ashanti S. Maxworth* and Mark Golkowski, Department of Electrical Engineerng, University of Colorado at Denver

Miniaturized Antenna System Designs and Characterizations for Wireless and Fully-Passive Brain-Machine Interface
(Commission K)
Lingnan Song* and Yayha Rahmat-Samii, Department of Electrical Engineering, University of California at Los Angeles

2016 USNC-URSI Meeting: January 6-9
This open scientific meeting was sponsored by the USNC-URSI. Through technical co-sponsorship of the meeting by the IEEE Antennas and Propagation Society, the authors of summaries that were presented at the meeting had the option of archiving their summaries on IEEE Xplore.

The USNC-URSI awarded a total of 106 travel fellowships to Boulder. On Wednesday, January 7, the committee held a student luncheon and a Reception for Women in Radio Science. Sixteen women attended the reception, and were able to network and exchange their experiences working in a highly male-dominated field.

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 2016 winners were:
