  • Patent number: 7834818
    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.
    Type: Grant
    Filed: March 31, 2006
    Date of Patent: November 16, 2010
    Assignee: Forschungszentrum Karlsruhe GmbH
    Inventors: Klaus Seemann, Harald Leiste, Viacheslav Bekker, Stefan Zils
  • Patent number: 7642098
    Abstract: A film and method of preparing a film. The film is made of at least one of ferromagnetic and ferrimagnetic material. An elongated slot is included in the material and is operable to control the domain structure of the material. The depth of the elongated slot is the same as the thickness of the film and the width of the elongated slot is greater than an exchange length of the material. The slot is free from contact with any side of the film.
