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., &#x2153;) 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.

RF shield and method for fabricating the same

Rotary drive apparatus includes first member journaled for rotation coupled by a cable to a second member also journaled for rotation, and at least one outer peripheral surface, on which the cable winds and unwinds, includes a smooth outer periphery. One of the rotatable members is the driving member, and the other rotatable member is the driven member.
