ABSTRACT:
A magnetostatic wave filter comprises a waveguide having a cut-off frequency region. In this waveguide, a YIG thin film is installed as a ferrimagnetic base material. Also, the cut-off frequency region of this waveguide comprises an attenuation band of the magnetostatic wave filter. Electromagnetic wave in the attenuation band of the magnetostatic wave filter is attenuated by this waveguide.
