Abstract:
A magnetostatic-wave device, comprising:a substrate;a ferri-magnetic member deposited on said substrate and having a generally planar major surface;a signal line having an input end for receiving an electric signal applied thereto and an output end for outputting said electric signal after it has propagated through said signal line, said signal line including at least first and second line sections extending over said major surface and being functionally coupled to said ferri-magnetic member, said first and second line sections being non-parallel to one another; anda magnetic field generator for generating a DC magnetic field which is oriented along a direction substantially parallel to said generally planar major surface so that said signal is outputted at said output end of said signal line in a filtered form when said DC magnetic field is applied to said magnetostatic-wave device.
