Patent ID: 7135643

Claim:
An apparatus for providing shielding from high frequency, electromagnetic interference, the apparatus comprising: an electrically-conductive shield adapted for covering at least a portion of a device having an operating frequency of about 2.5 gigabits per second, or an operating frequency within a range of about 7.5 gigabits per second to about 10 gigabits per second, the electrically-conductive shield including an electrically-conductive frame and at least one removable cover that is removably attached to the electrically-conductive frame; an electromagnetic absorbing material disposed on at least a first side of the at least one removable cover of the electrically-conductive shield, the electromagnetic absorbing material comprising a matrix including a silicone elastomer and an electrically absorbing carbonyl iron powder, where the thickness of the material and amount of carbonyl iron powder are tailored for absorbing at least a portion of electromagnetic energy having a frequency within a predetermined range of about 2000 megahertz to about 3000 megahertz, or about 7500 megahertz to about 10000 megahertz associated with the device, the electromagnetic absorbing material providing an improvement in attenuation of electromagnetic energy with respect to the device by at least about 6 decibels; wherein the at least one removable cover with the electromagnetic absorbing material disposed thereon is removable to thereby allow access to a device disposed under the electrically-conductive shield for replacement or upgrade of the device.
