LIGHTNING PROTECTION SHEET WITH PATTERNED DISCRIMINATOR
First Claim
1. A lightning protection sheet comprising an electrically conductive film having thickness t and an electrically non-conductive first discriminator layer having thickness TDL over the electrically conductive film, where the first discriminator layer is patterned into a plurality of features selected from the group consisting valley features having a depth d of between 50% and 100% of TDL, ridge-and-trench features having a trench depth d of between 50% and 100% of TDL, or combinations thereof.
