Abstract
Composite coatings, consisting of a ceramic barium hexaferrite and polyester, were manufactured byatmospheric plasma spraying. The crystalline structure of the barium hexaferrite was preserved duringthe spraying process while the polyester first (partly) melted and then resolidified. The high magneticlosses of the barium hexaferrite at mm-waves were coupled to the dielectric losses of the polyester in thecomposite coating and the superior electromagnetic absorption of the composite coating with respect tothe pure materials was determined
