1.The usage of Helmholtz resonator is restrained by the space, which is only available for rectangular resonator somewhile.
在实际应用中,共的使用往往受到安装空间的限制,有时候只能安装矩形。
2.Finally, in the micropolis corners you can see ring resonators, which are a conventional (non photonic-crystal) way to achieve a resonant cavity for use in channel-drop filters, etcetera.
3.The external inspirator is available to drive the resonator to produce traveling wave.Under resonant frequency the distortion of resonator reached a peak.
