Abstract (en)

The panel has at least three connected glass layers (1-3) with a layer of parallel electrical conductors (A) near the outer panel and at a defined angle to the direction of polarisation of the incident electromagnetic radiation. Layers (A,B) of fibre-shaped conductors are arranged between the central panel (2) and the outer (1) and inner (3) panels and at a distance apart so that the components radiated inwards and outwards differ in phase by an integral multiple of a quarter wavelength of the incident radiation. The conductor separation in the outer conductor layer is less than or equal to that in the inner layer.

Abstract (de)

Es wird eine radarabsorbierende Verbundglasscheibe beschrieben, die aus wenigstens drei miteinander verbundenen Glasschichten besteht, wobei zwischen der äußeren Scheibe und der mittleren Scheibe eine erste Schicht paralleler fadenförmiger elektrischer Leiter angeordnet ist und zwischen der mittleren Scheibe und der inneren Scheibe eine zweite Schicht fadenförmiger elektrischer Leiter vorgesehen ist, und wobei der Abstand der Schichten so bemessen ist, dass sich die von den beiden Schichten sowohl nach außen wie nach innen abgestrahlten Anteile in der Phase um n x /4 der Wellenlänge der einfallenden elektromagnetischen Strahlung unterscheiden. <IMAGE>
