  • Wind turbine and device for protecting from lightning
    Patent number: 10498125
    Abstract: A device for protecting from lightning (30) is intended to form at least a portion of an external surface of a structure to be protected and comprises a ground plane (32), a dielectric substrate (34) arranged on the ground plane, and an array of first metal elements (36) arranged on the dielectric substrate (34) and extending substantially parallel to the ground plane (32) in such a way that any pair of consecutive elements from said first metal elements (36) is separated by a distance comprised between 0.01 millimetres and 10 millimetres, said first metal elements being distributed in juxtaposed similar patterns, each of said patterns including first metal elements of different dimensions corresponding respectively to different electromagnetic resonant frequencies the juxtaposition of which defines an electromagnetic absorption band of the pattern.

  • Electromagnetic absorber
    Patent number: 9761953
    Abstract: The invention concerns an electromagnetic absorbent comprising: a metal earth plane, an insulating dielectric substrate, disposed on said metal earth plane, a set of metal resonant elements disposed on said insulating dielectric substrate, the electromagnetic resonant frequency of a resonant element being adjusted by adapting the dimensions of the resonant element, the set of resonant elements comprising resonant elements with different dimensions so as to enable the production, by juxtaposition of different electromagnetic resonant frequencies, of a predetermined electromagnetic absorption band. An elementary pattern formed by a plurality of metal resonant elements can be replaced periodically.
