Abstract

L'INVENTION SE RAPPORTE AUX DISPOSITIFS D'INTERACTION DE DEUX SIGNAUX A TRAITER PAR ONDES MAGNETOELASTIQUES. ELLE A POUR OBJET UN DISPOSITIF D'INTERACTION COMPORTANT UN SUBSTRAT NON MAGNETIQUE, UNE COUCHE MAGNETIQUE MINCE A PLAN FACILE, DEUX TRANSDUCTEURS PIEZOELECTRIQUES DISPOSES AUX EXTREMITES DE LA COUCHE MAGNETIQUE ET RECEVANT RESPECTIVEMENT LES DEUX SIGNAUX ELECTRIQUES A TRAITER. LES SIGNAUX APPLIQUES SONT CONVERTIS EN ONDES ELASTIQUES DE SURFACE QUI SONT TRANSMISES A LA COUCHE MAGNETIQUE SOUS FORME D'ONDES MAGNETOELASTIQUES QUI SE PROPAGENT EN SENS CONTRAIRES. LE DISPOSITIF EST SOUMIS A UN CHAMP MAGNETIQUE EXTERIEUR. LES VARIATIONS D'AIMANTATION DANS LA ZONE D'INTERACTION SONT RECUEILLIES PAR UNE PLAQUE DE DETECTION. L'INVENTION EST APPLICABLE, NOTAMMENT, POUR OBTENIR LE PRODUIT DE CONVOLUTION DES DEUX SIGNAUX A TRAITER.
