Resonator - Wikipedia
WEBA 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 ).
Resonator | Acoustic, Vibrations, Soundwaves | Britannica
WEBResonator, acoustical device for reinforcing sound, as the sounding board of a piano, the “belly” of a stringed instrument, the air mass of an organ pipe, and the throat, nose, and mouth cavities of a vocal animal. In addition to augmenting acoustic power, resonators may also, by altering relative.
7.8: Resonators - Physics LibreTexts
WEBResonators are distributed oscillators, i.e. structures that may sustain standing waves (in electrodynamics, oscillations of the electromagnetic field) even without an external source, until the oscillation amplitude slowly decreases in time due to unavoidable energy losses.
Resonator Definition & Meaning - Merriam-Webster
WEBnoun. res· o· na· tor ˈre-zə-ˌnā-tər. : something that resounds or resonates: such as. a. : a hollow metallic container for producing microwaves or a piezoelectric crystal put into oscillation by the oscillations of an outside source. b. : a device for increasing the resonance of a musical instrument.
Sound - Helmholtz Resonator, Acoustics, Vibrations | Britannica
WEBAn important type of resonator with very different acoustic characteristics is the Helmholtz resonator, named after the German physicist Hermann von Helmholtz. Essentially a hollow sphere with a short, small-diameter neck, a Helmholtz resonator has a single isolated resonant frequency and no other resonances below about 10 times that frequency.

WEBSep 16, 2022 · In this section we consider the resonator. Its function is to obtain a high light energy density and to gain control over the emission wavelengths. A resonator, whether it is mechanical like a pendulum, a spring or a string, or electrical like an LRC circuit, has one or multiple resonance frequencies νres. ν res..
Resonance - Wikipedia
WEBResonance is the phenomenon, pertaining to oscillatory dynamical systems, wherein amplitude rises are caused by an external force with time-varying amplitude with the same frequency of variation as the natural frequency of the system. [3]
9.4: Cavity resonators - Physics LibreTexts
WEBUnlike rectangular waveguides that propagate any frequency above cut-off for the spatial field distribution (mode) of interest, cavity resonators operate only at specific resonant frequencies or combinations of them in order to match all boundary conditions.
Resonator - an overview | ScienceDirect Topics
WEBJun 3, 2012 · A resonator is a device that allows the RF or MW energy from a source to be stored/confined so that there is a finite flux of electromagnetic energy within the confines of the resonator. It could be of reflection or transmission type and will allow the monitoring of changes in the AC magnetic susceptibility of the paramagnetic spin system ...
