Abstract

En elekfromagnetisk støyundertrykkende tynnfilm har en struktur som innbefatter en uorganisk isolerende matrise dannet av oksid, nitrid, fluorid eller en blanding derav og søylestrukturerte partikler dannet av et rent metall av Fe, Co eller Ni eller en legering som inneholder 20 vekt% av Fe, Co eller Ni og som er iimlefret i en uorganisk isolerende matrise.
