Abstract: A radome surface coating arrangement transparent to radiofrequency (RF) signals, the coating arrangement includes a first coating layer applied to and in physical contact with a radome surface and a second coating layer applied to and in physical contact with the first coating layer. The first coating layer includes nanoparticles capable of being heated by RF signals emitted through the coating arrangement. The second coating layer is a hydrophobic or superhydrophobic coating material devoid of the nanoparticles. The second coating layer covers the first coating layer.

Abstract: An article transparent to radiofrequency (RF) signals includes a substrate and a coating arrangement on the substrate. The coating arrangement includes a primer applied to and in physical contact with the substrate, a topcoat applied to and in physical contact with the primer layer, the topcoat including an organic polymer material, and nanoparticles dispersed throughout one of the primer and the topcoat. A content of the nanoparticles ranges from 0.1 wt % to 10 wt %.

Abstract: A method of fabricating a conductive composite wherein at least one predetermined electrical access area of a conductive material is coated with a maskant. The conductive material is included in a composite ply lay-up which is cured and then the maskant is removed from the conductive material.
