ABSTRACT:
A Faraday shield minimizes the leakage of electromagnetic interference (EMI) and radio frequency interference (RFI) of a maximum frequency and corresponding wavelength that emanates from electronic components contained within the shield. The top and bottom each contain apertures that are dimensioned to effectively block the escape of EMI and RFI from the shield and to permit the flow of air to dissipate heat without generating acoustic noise. The thickness of the top of the shield is at least one half of the diagonal length across the largest of the apertures located in the top. The length of the longest aperture side is less than one fourth of the wavelength of the maximum frequency of EMI and RFI contained by the shield. Corresponding relationships exist between the apertures located in the shield bottom and its thickness.
