ABSTRACT:
A magnetostatic wave resonator having a transducer oriented such that it is tangent at all points to a wavefront of a traveling wave component of a resonant mode of the resonant cavity. In a rectangular cavity of width L.sub.x and length L.sub.y, the transducer is perpendicular to the wavevector k=(m.pi./L.sub.x)e.sub.x +(n.pi./L.sub.y)e.sub.y for some nonzero integers m and n, whereby the transducer optimally transfers energy into the resonant mode that is a linear superposition of travelling waves that includes this wavevector. This enhances coupling into the resonant mode of interest and reduces the amount of coupling into spurious modes.
