摘要

Functionalized honeycomb structure, sandwich composite structure, manufacturing process, optimization process and associated devices The present invention relates to an absorbent structure which is a honeycomb-like cellular structure (10) extending between two end faces and which comprises tubular cells (12), each cell (12) comprising walls (14 ) delimiting said cell (12), the walls (14) extending between the two end faces, the walls (14) being formed of a dielectric material, at least one cell (12) comprising at least one strip ( 16) of electrically conductive coating disposed in at least one wall (14) or on a surface of at least one wall (14), the honeycomb structure (10) being characterized by parameters chosen so that the absorbent structure provides an attenuation of at least 10 dB for each incident wave of a frequency range having a frequency range greater than or equal to 15 GHz.
