Abstract

Anordbarer Retroreflektor für die Reflexion von elektromag­ netischen strahlen, der dazu geeignet ist, elektromag­ netische Strahlung, die zur nachhaltigen Beeinflussung magnetischer oder sonstiger Datenträger geeignet wäre, durch Reflexion oder Absorption zu zerstören, wobei der Retroreflektor als Flächenbahn (100), die aus einer Grundschicht (10) von aus einem Metall ausgebildeten, nebeneinander angeordneten Reflektoren mit darauf aufgebrachten Filterschichten (50;150) aus einem geeig­ neten metallischen Werkstoff besteht und auf einer Unterseite (10a) und auf einer Oberseite (10b) mit einer Deckschicht (30,40) versehen ist, ausgebildet ist Arrangeable retroreflector for the reflection of elektromag netischen rays, which is suitable for electromag netic radiation that has a lasting influence magnetic or other data carrier would be suitable, destroy by reflection or absorption, whereby the retroreflector as a sheet (100) made of a base layer (10) made of a metal juxtaposed reflectors with on it applied filter layers (50; 150) from a suitable neten metallic material and on a Underside (10a) and on an upper side (10b) with a cover layer (30, 40) is provided is
