EMIR is a system used to map electromagneticfields using infrared... In the background, an electromagneticfield in a hyperbolic antenna... However, Onera researchers have successfully developed a system to visualize electromagneticfields (combining an electric field and a magnetic field)... The heating is proportional to the energy of the electromagneticfield: the stronger the field, the more the film heats up
Today, researchers at Onera are using it to improve their testing systems in the electromagneticsfield... Not forgetting lightning, which has direct impact on structures, and also indirect impact due to the strong electromagneticfields that it induces... They need very intense electromagneticfields to be created in order to approach the critical conditions for the equipment
Magnetic field mapping in the launcher area in the event of impact on one of the towers and representation of the meshing used for the simulation of electromagneticfields and currents following a lightning strike. Share
Free electrons and positive ions can however appear if the gas is subject to an electric field of strong intensity, to sufficiently high temperatures, to a bombardment particles or to a very intense electromagneticfield. When ionization is so important that the number of electrons per unit of volume is comparable with that of the neutral molecules, the gas becomes a plasma, which is a very conducting fluid
View of the electromagneticfield using infrared thermography... This is a technology that has matured slowly, at the rate of successive scientific breakthroughs, and whose field of application extends beyond the scope of aeronautics: characterization of innovating antennas, diagnosis of existing equipment, prevention against electromagnetic aggressions, etc
