Abstract
The invention concerns an electromagnetic shielding panel for attenuating electromagnetic radiation typically in the frequency range 20 MHz to 10,000 MHz. In one embodiment of the invention, the panel comprises a laminate of two panes of glass one of which includes an electroconductive coating sandwiched between the two sheets of glass is a plastics interlayer (i) into which is embedded four strips of fine electroconductive mesh which lie along the edge of the laminate and which are in electrical contact with the coating. In another embodiment of the invention, the coated glass includes peripheral bus bars which are in electrical contact with the coating. The mesh and bus bars are arranged to make electrical contact with a metal frame which may be earthed. Alternatively, no direct mechanical contact is made between the frame and the coating and a capacitive coupling (cc) suffices.
