Abstract
A shielded substrate is disclosed which has a randomly oriented, non-linear conductive pattern formed on at least one surface of the substrate. The conductive pattern provides excellent EMI-RFI shielding and visual opacity properties without generating moire patterns. The conductive pattern is formed of a series of interconnecting non-linear, conductive elements, such as circles, ovals, ellipses and polygonal shapes. The conductive substrate may be formed through the use of photolithography process.
