| 1. | Reversed time - Time-Reversed Electromagnetics - Zoom in the Lab |
| | Reversed TimeIn an environment overloaded with electromagnetic waves, checking the electromagnetic compatibility of systems is a major issue... To perfect electromagnetic compatibility tests, Onera researchers have adapted a technique developed over the last few years in acoustics, time reversal.. It was first perfected for acoustic waves by the Mathias Fink's team at the École supérieure de physique et chimie industrielles (Graduate School of Industrial Physics and Chemistry).... |

| | This structure, an assembly of dielectric tubes and conductors, is a meta-material that can be given specific transmission, reflection, refraction or diffraction properties of electromagnetic waves.... The level of control obtained on plasmas, with respect to their production with low power consumption budget and possibilities of acting on electromagnetic waves and the availability of validated models, means that we can consider several applications in the field of stealth and antennas (controllable meta-materials).... |
