Shielding Properties of Welded and Unwelded Wire Mesh Enclosures

In this article, the shielding properties of wire mesh enclosures are studied, with emphasis on the importance of electrical contact between crossing wires. Experimental results are combined with numerical three-dimensional simulations to provide conclusions about the shielding effectiveness in a wide frequency range and how it depends on the contact conditions between crossing wires and between the wire mesh and a possible enclosure frame.
