Approaching both infinities through electromagnetic waves

The URSI-France 2019 Workshop, under the sponsorship of the Académie des sciences, will be dedicated to “Approaching both infinities through electromagnetic waves”. The workshop will be held at Observatoire de Versailles Saint-Quentin (20 minutes train from Paris), March 26th-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. Observation of the complexity of the living world will also have its place.

The workshop will be organized around oral and poster sessions. Most of the 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.
