A novel approach to the suppression of magnetostatic modes in layered Ca-doped/pure yttrium iron garnet (YIG) films is presented. By properly selecting the position and width of the broad background signal excited in the Ca: YIG layer, the magnetostatic spectrum of the coupled pure YIG can be drastically modified. In particular, selecting a proper calcium concentration of the damping layer, an entire surface or volume mode band can be suppressed. In this paper, experimental results for double-layered films are reported. An extension to triple-layered films, allowing the total suppression of all modes but one, is also proposed.
