ABSTRACT:
A magnetostatic wave device comprises two YIG thin films as a ferrimagnetic base material. At one side of the YIG thin films, a microstrip line is disposed so as to intersect orthogonally with the main surfaces of the YIG thin films. At the other side of the YIG thin films, a ground conductor is disposed so as to intersect orthogonally with the main surfaces of the YIG thin films. A d.c. magnetic field is applied in a direction which is parallel to the main surfaces of the YIG thin films and orthogonal to the main surface of the microstrip line.
