Approaching both infinities through electromagnetic waves

Call for papers

The URSI-France 2019 Workshop, under the sponsorship of the Académie des sciences, will be dedicated to “Approaching the two infinities through electromagnetic waves”. The workshop will be held at the Observatoire de Versailles Saint-Quentin-en-Yvelines (OVSQ), located in Guyancourt, near Paris, on March 26th and 27th, 2019.

The workshop will also be the opportunity to celebrate the 100th anniversary of the International Scientific Unions (IAU, IUPAC, UGGI and URSI).

Electromagnetic waves, through their wide range of wavelengths, constitute a privileged means for exploring the two infinities: the infinitely great that concerns the large structures of our universe as well as the infinitesimal that concerns the fundamental bricks of which this same universe seems to be made. Beyond the multi-scale aspect of the proposed theme, there will be the question of energetic limitations of exploration means, detection, measurement and imaging capabilities, but also that of computing means allowing us to better understand and master all these phenomena. The observation of the complexity of the living world will also have its place.

The workshop will be organized around oral and poster sessions. Most sessions will be introduced by invited speakers, presenting the state of the art and / or recent developments, followed by talks that have been selected by the Scientific Committee. The working languages will be French and English.

Main topics:                                                         

  • Propagation at large and very large distance, space observation, radio telescopes;
  • Role of optics and EM waves in the detection of ultra-weak signals, application to gravitational waves;
  • Exploration by very low frequencies, terahertz waves, ultra-fast pulses;
  • Phenomena related to waves in plasmas, RF wave and microwave probing, application to fusion plasmas;
  • Subwavelength imaging, microscopic imaging of the living and the cell;
  • Electromagnetic manipulation of quantum states, quantum computer;
  • Multiscale physics, hybrid methods.


The Workshop will be held at the Observatoire de Versailles Saint-Quentin-en-Yvelines (OVSQ) in Guyancourt (78) (http://www.ovsq.uvsq.fr/), Tuesday 26 and Wednesday 27, March 2019. It will include on Wednesday, March 27th, the URSI-France General Assembly.

CNFRS/URSI-France Medall and Radiosciences PhD Awards

The workshop will be the opportunity to remit the annual URSI-France Medal, as well as the 2019 Radiosciences PhD Award under the aegis of URSI and URSI-France.

European Young Scientist Grant

A Young scientific grant of 300 euros and free registration will be awarded to the principal author and presenter of the best article, if he is under 35 and affiliated to a European laboratory other than French.


The texts of the communications will be grouped together in proceedings, an electronic version of which will be available on this site.

A selection of papers will be proposed for publication, either in a thematic issue of the Comptes rendus Physique de l’Académie des sciences or in the Revue de l’électricité et de l’électronique (REE).

Instructions for authors

Proposals for papers should be submitted online via the website: https://ursifr-2019.sciencesconf.org/, in the form of a clear and concise text of one to two pages, with sufficient content to allow their scientific evaluation. For further information on paper submission, see Template in  WordOpenOffice or LateX

For, in fact, what is man in nature? A Nothing in comparison with the Infinite, an All in comparison with the Nothing, a mean between nothing and everything. Since he is infinitely removed from comprehending the extremes, the end of things and their beginning are hopelessly hidden from him in an impenetrable secret; he is equally incapable of seeing the Nothing from which he was made, and the Infinite in which he is swallowed up.

Pascal, the Pensées, 1670
