Abstract
A shielding apparatus has first and second electrically conductive sheets attached to an interior of a housing. A gap between the first and second electrically conductive sheets has a size based on a predefined desired cutoff frequency, and the widths of the first and second electrically conductive sheets are no more than twice the size of the gap. The lengths of the first and second electrically conductive sheets are at least four times the size of the gap.
