Magnetostatic wave device.

摘要

This magnetostatic wave device includes a ferrimagnetic substrate (14) like, for example, a YIG thin film. On this ferrimagnetic substrate a strip line (18) is formed. One end of the strip line is connected to an input terminal and the other end is connented to an output terminal. A magnetic field (Ho) is applied to the ferrimagnetic substrate by a magnet. In this case, the ferrimagnetic substrate is so disposed that a direction parallel to its principal plane and a direction perpendicular to its principal plane are not parallel to the direction of a line of magnetic force of the magnet. <IMAGE>
