Electromagnetic shielding panel
First Claim
1. An electromagnetic shielding panel comprising in combination;
- first and second panes, each independent, of glass or plastics said first and second panes each having major inner and outer surfaces thereof, and being positioned in opposed spaced parallel relationship;
and, first and second electroconductive coatings, said first electroconductive coating being located on the major outer surface of the first pane of glass or plastics and the second electroconductive coating being located between the first and second panes of glass or plastics, wherein the second electroconductive coating is electrically coupled to the first electroconductive coating so that, in use of the shielding panel, direct electrical connection to the first electroconductive coating to enable said first electroconductive coating to be connected to earth also provides for the connection of the second electroconductive coating to earth to provide effective attenuation of electromagnetic radiation in the path of the shielding panel while providing good optical qualities.

Abstract
An electromagnetic shielding panel incorporates at least two electroconductive coatings. In two of the panels the coatings are carried on separate sheets of float glass one of the coatings being an anti-abrasive coating is on the outermost surface of the glass in the panel arrangement while the other coating being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass in the panel arrangements. In other panel arrangements the two coatings are located on opposing sides of one glass sheet and in two of the panels a plain sheet of float glass is employed to protect the soft silver coating. In another panel a sheet of glass carrying an anti-abrasive coating is employed. The panels are of the double glazed and the laminated type. This invention utilizes the enhanced capacitive coupling between the two coatings to effectively earth the innermost silver coating by way of the anti-abrasive coating without any direct electrical connection being required to be made to the innermost coating.
