A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators … See more A physical system can have as many resonant frequencies as it has degrees of freedom; each degree of freedom can vibrate as a harmonic oscillator. Systems with one degree of freedom, such as a mass on a spring, See more Mechanical resonators are used in electronic circuits to generate signals of a precise frequency. For example, piezoelectric resonators, commonly made from See more • Coupling coefficient of resonators • Crab cavity • Nuclear magnetic resonance • Optical ring resonators • Superconducting RF See more Resonant circuits An electrical circuit composed of discrete components can act as a resonator when both an inductor and capacitor are included. Oscillations are limited by the inclusion of resistance, either via a specific resistor component, or due to See more The most familiar examples of acoustic resonators are in musical instruments.

WebA bulk acoustic wave (BAW) resonator includes: a substrate; a piezoelectric layer disposed above the substrate; a first electrode disposed below the piezoelectric layer and including a first portion and a second portion spaced apart from each other; a second electrode disposed above the piezoelectric layer; a first dielectric layer, a second dielectric layer, … WebSurface acoustic wave (SAW) devices are key components for sensing applications. SAW propagation under a periodic grating was investigated in this work. The theoretical method used here is the space harmonic method. We also applied the results of SAW propagation studied in this work to design a two-port resonator with an Al grating on ST-cut quartz. … hafermehl coop
