It is commonly designated as URS! (from its French name, Union Radio Scientifique Internationale). Its aims are (l) to promote the scientific study of radio communi cations, (2) to aid and organize radio research requiring co operation on an international scale and to encourage the discussion and publications of the results, (3) to facilitate agreement upon common methods of measurement and the standardization of measur ing instruments, and (4) to stimulate and to coordinate studies of the scientific aspects of telecommunications using electro magnetic waves, guided and unguided. The International Union itslef is an organizational framework to aid in promoting these objectives. The actual technical work is largely done by the National Committees in the various countries. The officers of the International Union are: President: Prof. W. N. Christiansen (Australia) Past President: M. J. Voge (France) Vice-Presidents: Prof. W. E. Gordon (USA) Dr. A. P. Mitra (India) Prof. A. Smolinski (Poland) Prof. F. L. Stumpers (Netherlands) Secretary General: Prof. P. Hontoy (Belgium) Honorary Presidents: H. G. Booker (USA) B. Decaux (France) W. Dieminger (West Germany) J. A. Ratcliffe (UK) R. L. Smith-Rose (UK) The Secretary's office and the headquarters of the organi zation are located at Rue de Nieuwenhove, 81, B-1180 Brussels, Belgium. The Union is supported by contributions (dues) from 36 member countries. Additional funds for symposia and other scientific activities of the Union are provided by !CSU from contributions received for this purpose from UNESCO. The International Union, as of the XVIII General Assembly held in Lima, Peru, August 1975, has nine bodies called Commissions for centralizing studies in the principal technical fields. The names of the Commissions and the chairmen and vice chairmen follow. A. Electromagnetic Metrology Chairman: Prof. S. Okamura (Japan) Vice-Chairman: Prof. V. Koss (West Germany) B. Fields and Waves Chairman: Prof. L. B. Felsen {USA) Vice-Chairman: Prof. H. G. Unger (West Germany) C. Signals and Systems Chairman: Prof. V. Zima (Czechoslovakia) Vice-Chairman: Dr. J. K. Wolf (USA) D. Physical Electronics Chairman: Prof. G. W. Farnell (Canada) Vice-Chairman: Dr. J. LeMezec (France) E. Electromangentic Noise and Interference Chairman: Mr. G. Hagn (USA) Vice-Chairman: Prof. S. Lundquist (Sweden) F. Wave Phenomena in Non-ionized Media Chairman: Prof. A. T. Waterman {USA) Vice-Chairman: Dr. D. Gjessing (Norway) G. Ionospheric Radio and Propagation Chairman: Dr. B. Hultqvist (Sweden) Vice-Chairman: Dr. P. Bauer (France) H. Waves in Plasmas Chairman: Prof. F. W. Crawford (USA) Vice-Chairman: Dr. M. Petit (France) J. Radio Astronomy Chairman: Prof. H. Tanaka (Japan) Vice-Chairman: Dr. V. Radhakrishnan (India) Every three years, the International Union holds a meeting called the General Assembly. The next General Assembly, the XX will be held in Washington, D.C., USA in August 1981. The Secretariat prepares and distributes the Proceedings of these General Assemblies. The International Union arranges inter national symposia on specific subjects pertaining to the work of one Commission or to several Commissions. The International Union also cooperates with other Unions in internattonal symposia on subjects of joint interest. Radio is unique among the fields of scientific work in having a specific adaptability to large-scale international research programs, for many of the phenomena that must be studied are worldwide in extent and yet are in a measure subject to · control by experimenters. Exploration of space and the extension of scientific observations to the space environment is dependent on radio for its communication link and at the same time expands the scope of radio research. One of its branches, radio astron omy, involves cosmos-wide phenomena. URSI has in all this a distinct field of usefulness in furnishing a meeting ground for the numerous workers in the manifold aspects of radio research; its meetings and committee activities furnish valuable means of promoting research through exchange of ideas.
