Abstract: An electromagnetically shielded enclosure that is portable and lightweight with a double perimeter entry seal. The electromagnetically shielded enclosure can be used for applications such as testing and security and can be scaled from a bench top unit to a large field deployed enclosure. The electromagnetically shielded enclosure has a novel entry seal that eliminates the electromagnetic leakage that is common around the entry areas of such enclosures. The entry seal of the electromagnetically shielded enclosure is made up of a door having a first perimeter closure material and a second perimeter closure material and an enclosure opening having a first perimeter closure and a second perimeter closure where the first perimeter closure material aligns with the first perimeter closure and the second perimeter closure material aligns with the second perimeter closure. This double perimeter entry seal provides for electromagnetic isolation within the electromagnetically shielded enclosure.

Abstract: An electromagnetically shielded enclosure with operable interfaces that is portable and lightweight. The electromagnetically shielded enclosure has operable interfaces including a tactile interface through the shielding material and optionally a shielded tactile window for viewing of a secured electronic device and also for operating the secured electronic device should it have a touch screen. An internal frame is optionally provided that prevents conductive interference of a secured electronic device touch screen by the shielded tactile window. An input/output assembly is further provided to allow signals and power to be brought in or out of the enclosure to connect with the secured electronic device without compromising radio silence.
