摘要： A structure (and method) for tuning a resonant structure, includes a resonant structure including either a predetermined material coating provided on either a bar or a cantilever, or a lightly doped single crystal semiconductor material, and a circuit for providing a variable field adjacent the resonant structure, with the length or at least one of the elastic constants of the resonant structure changing with the application of the variable magnetic or electric field, respectively, thereby to selectively tune the resonant structure.

摘要： A magnetostatic wave filter that includes a ferromagnetic substance stacked on one side of a dielectric substrate, one side of which is grounded, and the filter includes an input section having an input transfer line and an input energy transformer for causing the energy transformation between an electromagnetic wave and a magnetostatic wave, and an output section having an output energy transformer for causing the energy transformation between the electromagnetic wave and the magnetostatic wave and an output transfer line. The width of exciting lines in the input energy transformer and the output energy transformer varies in a longitudinal direction, the filter includes a shield film formed of a grounded conductive film having holes through which a magnetic thin film can pass between the input section and said output section, to prevent coupling of an electromagnetic wave.
