  This work reports the design, fabrication, and characterization of
coupling-enhanced magnetostatic forward volume wave resonators with significant
spur suppression. The fabrication is based on surface micro-machining of
yttrium iron garnet (YIG) film on a gadolinium gallium garnet (GGG) substrate
with thick gold transducers. A distributed resonator is used to excite forward
volume waves in YIG to realize a frequency dependent coupling boost. Fabricated
devices at 18 GHz and 7 GHz show coupling coefficients as high as 13$\%$ and
quality factors above 1000. Higher-order magnetostatic mode suppression is
experimentally demonstrated through a combination of transducer and YIG
geometry design. An edge-coupling filter topology is proposed and simulated
which utilizes this novel distributed magnetostatic resonator.
