In literature:

First, by direct muscular effort, the wrong way; second, by expansion and inflation, the added resonance of air in the cavities, the right way.
"The Renaissance of the Vocal Art" by Edmund Myer
Red lines denote division of the breath in the resonance of the head cavity, high range.
"How to Sing" by Lilli Lehmann
HEAD CAVITIES, a resonator for the voice, 6; effect of, on resonance, 12.
"Resonance in Singing and Speaking" by Thomas Fillebrown
Whether or not the head cavities act as resonators is one of the many mooted points in voice training.
"The Head Voice and Other Problems" by D. A. Clippinger
According to this view these chambers are not properly resonators but sounding cavities.
"Voice Production in Singing and Speaking" by Wesley Mills
The resonance in the head cavities is soon perceived by those who are beginning to sing.
"Caruso and Tetrazzini on the Art of Singing" by Enrico Caruso and Luisa Tetrazzini
Whether the tone produced be right or wrong, the influence of the resonance cavities is about the same.
"The Psychology of Singing" by David C. Taylor
It is not contended that these diagrams picture the actual form assumed by the resonance cavities very accurately.
"The Child-Voice in Singing" by Francis E. Howard
The resonance of the mouth cavity is also of great importance.

What is true of the cup also is true of the resonance-cavities.

In news:

The sample is loaded into a high-frequency resonant cavity in a slowly varying uniform magnetic field.

In science:

This effect is observed when the rate of expansion is so high that, as resonance is approached, the cavity doesn’t have enough time to completely fill itself.
Finesse and mirror speed measurement for a suspended Fabry-Perot cavity using the ringing effect
The transmitted power is shown as a function of time as the cavity length sweeps the optical resonance at an unknown rate.
Finesse and mirror speed measurement for a suspended Fabry-Perot cavity using the ringing effect
Fig.3: The calculated Fabry-Perot transmitted power, with F = 4000, as a function of cavity length ∆L as the resonance is swept at v = 0 (static approximation), v = 1λ/s, and v = 2.6λ/s.
Finesse and mirror speed measurement for a suspended Fabry-Perot cavity using the ringing effect
The authors of Ref. realized at the time that coherent lasing requires a resonator (cavity).
Coherent Random Lasing and "Almost Localized" Photon Modes
They conjectured that, in the absence of traditional well-defined resonator (as in a semiconductor laser), the cavities in polycrystalline films are “self-formed” due to strong optical scattering.
Coherent Random Lasing and "Almost Localized" Photon Modes
In an open sample, of size L much smaller than the two-dimensional localization length ξ, the almost localized states correspond to sharp resonances, residing in the high-Q ring-shaped cavities, as discussed throughout the paper.
Coherent Random Lasing and "Almost Localized" Photon Modes
Such a cavity with one or few atoms in a configuration of far-off-resonant interactions provides an effective Kerr nonlinearity for the input light [10,13,14], as was first observed in Ref. .
Scalable photonic quantum computation through cavity-assisted interaction
Design studies are in progress at Michigan State University (MSU) for a 10th-harmonic driver linac consisting of quarter-wave resonators (QWRs), half-wave resonators, and elliptical cavities .
Niobium Quarter-Wave Resonator Development for The Rare Isotope Accelerator
The quarter-wave resonators developed by Legnaro for ALPI are the basis for the design of the RIA quarter-wave cavities.
Niobium Quarter-Wave Resonator Development for The Rare Isotope Accelerator
RF testing was done with the cavity immersed in a liquid helium bath at 4.2 K; some additional measurements were done at 1.5 K or 2 K. A phase feedback loop was used to lock onto the resonance.
Niobium Quarter-Wave Resonator Development for The Rare Isotope Accelerator
FIG. 2: (a) Atomic level structure: levels |ai (|bi) and |ui are coupled by a laser (cavity mode) off resonance. (b) After adiabatic elimination of the upper state |ui, we are left with a Jaynes–Cummings type of Hamiltonian, where states |a, ni and |b, n + 1i are coupled.
Sequential generation of entangled multi-qubit states
For the set of parameters used here, the cavity develops a period-one and period-four resonance islands whose boundaries are shown with thick lines in Fig. 1(b).
Design of switches and beam splitters using chaotic cavities
It has been shown3, 4 that when the cavity of the waveguide of Fig. 1(a) is characterized by an incomplete horseshoe the conductance GLR (= GRL ) fluctuates strongly with sharp resonances.
Design of switches and beam splitters using chaotic cavities
Notice that under resonance conditions the cavity acts as a resonator.
Design of switches and beam splitters using chaotic cavities
Now, the idea is to attach transversal ports to the cavity in order to guide the QBS out of the waveguide (once they are excited by the appropriate resonance energy) to construct switches and/or beam splitters.
