Microwave limiter filters created on the base of spherical YIG-monocrystal resonators use the effect of parametric excitation of spin waves (SW), that obstructs the increasing of the microwave power passed through the resonator [1]. Such devices have principally narrow band and the possibilities of the expansion of their operating range are extremely limited. Planar systems like a microstrip line on the substrate of epitaxial YIG-GGG structures were shown to have wider band [2].
