  • Voltage dividing shielded door seal
    Patent number: 4677251
    Abstract: A door seal used in shielded enclosures for ensuring that high and low frequency electromagnetic waves are not allowed to pass through the shielded enclosure. One portion of the door seal contains a cavity having a dielectric material therein. Additionally, a small gap is provided in the periphery surrounding the cavity such that a voltage dividing network is established in the door seal for attenuating the effect of any high frequency or low frequency electromagnetic wave which would pass in either direction through the seal.
