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.
