The present invention relates to an electromagnetic shielding device including at least one hollow protective textile sleeve having a main rest diameter D1 and an interior volume configured to receive one or several elongated element(s), and at least one hollow connecting textile sleeve having a rest diameter D2, D2 greater than Dl. The protective textile sleeve includes a substantially annular front part having a front open end, the connecting textile sleeve includes a substantially annular rear part having a rear open end, and the shielding device includes a first electrically conductive securing area in which the rear part of the connecting sleeve and the front part of the protective sleeve are at least partly secured.

This invention provides an EMF/RF radiation shielding means including a conductive fabric enclosure functioned as a Faraday cage, a pair of flexible magnets for sealing the Faraday cage and a zipper to complete the closure and allow the two magnets to connect. The conductive fabric enclosure has a closable and openable top side, a left side, a right side and a closed bottom side. The conductive fabric enclosure is provided with two accommodations opposite to each other at its inner surface under and along the closable and openable top side. The pair of flexible magnets is respectively placed in the accommodations for connecting and sealing the Faraday cage. The zipper provides easy closing and opening to the enclosure, where the zipper closes it allows the two magnets to connect and when opening it allows easy access to the enclosure.

It is disclosed an electromagnetic shield (1) and a related method for providing electromagnetic shielding wherein the shield comprises a shielding surface provided with a plurality of electrically conductive elements (2), said plurality of electrically conductive elements (2) being electrically connected to a switching assembly (3) configured to switch said electromagnetic shield (1) between an open configuration, wherein said electrically conductive elements (2) are electrically insulated from one another, and a shorted configuration wherein said electrically conductive elements (2) are electrically connected to each other at a common node (C). When the electrically conductive elements (2) of the electromagnetic shield (1) are switched between the open and shorted configurations, a change of the electromagnetic shielding effectiveness (EMSE) occurs. The electromagnetic shield (1) can be used for providing a shielding textile fabric (12), or an article that may comprise the electromagnetic shield (1) in form of a pocket preferably made with the shielding fabric (12).
