A variational formula is presented for magnetostatic wave resonators. The formula is applied to the magnetized ferrite disk and ring resonators. The resonant mode charts are shown, and it is found that if the aspect of the resonator is optimized, a single mode resonance can be realized on a wide frequency range.
