  • Publication number: 20240431082
    Abstract: A self-adaptive shielding device is suitable for a lens or a window of a piece of equipment provided with an electrically conductive enclosure containing an optical or RF sensor. The device includes a shielding screen having a switchable RF shielding mesh of micrometric pitch at least partially surrounded by a border of insulator-metal transition material arranged between the mesh and an electrically conductive envelope. A susceptor element is arranged facing the insulator-metal transition material and transforms incident electromagnetic energy (RFH) into activation heat for the insulator-metal transition material. The susceptor element causes a transition to the conductive state of the insulator-metal transition material under the action of the electromagnetic energy so as to electrically connect the mesh to the electrically conductive envelope when the incident electromagnetic energy exceeds a given threshold.
