Guides & Networks

The activity of the OR GUIDES & NETWORKS is globally related to two thematic fields: flow and wall effects in waveguides on the one hand, and guided waves, networks and metamaterials on the other hand. The notion of waveguide, common to these two main axes, is the basis of the thematic unity of the OR.

 

Guiding with flow : wall effects (liners-impedance, corrugations, perforated plates, measurement benches, non-reciprocal reflection, black hole lasers)
