ABSTRACT:
A device for attenuating reflections of an electromagnetic wave impinging thereon and a method of making the device. The device includes a structured film comprised of at least one of a ferromagnetic and ferrimagnetic material. The structured film has a structure and a uniform film portion of the at least one of a ferromagnetic and ferrimagnetic material underneath the structure such that the structured film has at least two different resonance frequencies.
