Abstract
Methods and apparatus for providing a frequency selective limiters (FSL) having a free-standing Yttrium Iron Garnet (YIG) film with first and second opposing surfaces. A metal plane is disposed on one surface of the YIG film to provide the YIG film with a metalized surface. At least one transducer is disposed on the other surface of the YIG film with a respective ends coupled to the metalized surface of the YIG film.
