Abstract

Elemento de seguridad para la vigilancia electrónica de artículos que comprende por lo menos dos materiales (1; 2) de alta permeabilidad que, cuando son excitados por un campo magnético externo (H), emiten cada uno de ellos una señal característica (CS 1; CS2), y en el que los componentes de la señal máxima de los dos materiales (1; 2) se sitúan en distintos márgenes de frecuencia (F1; F2), y los componentes de la señal de un material (1; 2) son de un valor despreciable en este margen particular de frecuencia (F2; F1), en el que el componente de la señal del otro material (2; 1) alcanza un nivel máximo.
