Abstract:
1. An electromagnetic shield for a room or for a building, the shield comprising overlapping, conductively connected and electrically conductive mesh or grid sections, which are electrically grounded, each of the mesh or grid sections having an overall length along a first axis and an overall width along a second axis that is orthogonal to the first axis, wherein at least one mesh or grid section includes a longitudinal fold having a first dimension along the first axis and a second dimension along the second axis and a lateral fold having a first dimension along the first axis and a second dimension along the second axis, the first dimension of the longitudinal fold being less than the overall length by at least the first dimension of the lateral fold and the second dimension of the lateral fold being less than the overall width by at least the second dimension of the longitudinal fold, and wherein the at least one mesh or grid section overlaps at least one adjacent mesh or grid section along the longitudinal fold and at least one other adjacent mesh or grid section along the lateral fold, such that the folds of the at least one mesh or grid section and adjacent mesh or grid sections interlock like hooks in a cross sectional view.
