  • Patent number: 7371977
    Abstract: An RF shield is fabricated from a solid piece of metal or metal alloy. Holes are cut through the metal or metal alloy at fixed positions to form an array. The diameter of the holes is selected to be significantly smaller than the RF wavelength (e.g., ?) it is designed to prevent from passing through the holes. The thickness of the plate (length of the holes) establishes the attenuation of the shield. The number of holes establishes the air or other fluid throughput.
