LAMINATED SHIELD Russian patent published in 2002 - IPC

FIELD: protection of electronic devices and personnel from radio-frequency electromagnetic radiation in various industries. SUBSTANCE: proposed laminated shield transparent in visible spectrum of light has at least one additional layer of transparent insulating material placed either on shield surface free from electricity conducting layer, or on electricity conducting layer surface, or at least one additional layer of transparent insulating material is placed on each side of shield. Permittivity of transparent insulating layers reduces with increase in their distance from electricity-conducting layer and surface resistance of electricity conducting layer is 30-60 Ohms per square. EFFECT: reduced fraction of radio-frequency radiation reflected from shield. 5 cl, 1 dwg
