Abstract:
Magnetostatic devices, comprising:input and output electrodes for including energy conversion pattern provided on a dielectric substrate; a multi-layer magnetic substance structure placed at an upper portion of said dielectric substrate, wherein magnetically active thin film is placed at both sides of a magnetically inactive substrate; an upper shield, composed of grounded conductor, for preventing said input and output electrodes from electromagnetic coupling; a lower shield provided at said dielectric substrate, wherein said substrate contains a hole with the same length as the upper shield, and walls of said hole are provided with a conductor; a magnetostatic wave terminator, inserted onto said dielectric substrate to be placed at both end planes of said multi-layer magnetic structure, for absorbing said magnetostatic wave not to reflect therefrom; and a magnetostatic wave reflector, provided on said dielectric substrate as a line with a variable width, for reflecting and selecting a desired pass frequency band before it reaches to said mangnetostatic wave terminator.
