Abstract
A device for protecting from lightning () is intended to form at least a portion of an external surface of a structure to be protected and comprises a ground plane (), a dielectric substrate () arranged on the ground plane, and an array of first metal elements () arranged on the dielectric substrate () and extending substantially parallel to the ground plane () in such a way that any pair of consecutive elements from said first metal elements () 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.
