resonance frequency

1 in an ultrasound transducer, the frequency for which the response of a transducer to an ultrasound beam is a maximum.
2 the frequency at which the transducer most efficiently converts electric signals to mechanical vibrations.
3 (in magnetic resonance) the frequency at which a nucleus absorbs radio energy when placed in a magnetic field.

When using the resonance frequency for flexural vibration in the third or fourth mode, however, it is promising that the Young's modulus and shear modulus can be measured by the combination of the flexural and longitudinal vibration methods while reducing the influence of depth/length ratio of the specimen similarly to the aforementioned methods.
Optical micrographs at several scales and resonance frequency measurements of the cantilevers are suggested as monitoring tools.
Establishing a relationship between torque, attachment location, and resonance frequency with mechanical pushout forces would provide valuable information as a basis for further in vivo testing, because currently no biomechanical testing data directly relate resonance frequency to load bearing.
The multihead weigher is able to optimize the resonance frequency of all its vibratory feeders in less than 30 seconds, ensuring a consistent high capacity.
The NMR resonance frequency [omega] depends on the Larmor frequency
The glass should have an almost perfectly round cross-section so that its resonance frequency is in the correct vocal range.
It is in effect a frequency dependent strain gauge operating at ultrasound frequencies and consists of a transducer mounted on the mixer's rotating shaft to monitor variations in its resonance frequency as the torsional load varies.
This study focused on microbalances based on piezoelectric crystals, where a decrease of the resonance frequency is correlated to the mass accumulated on its surface.
He points out that the navy has known the resonance frequency of airspaces in Cuvier's beaked whales since 1998 and places the resonance frequency in the whales' cranial airspaces at about 290 hertz at 500 meters depth--precisely the middle frequency of the LFA system.
Further, says the manufacturer, its new generators are capable of recognizing the resonance frequency of the converter/booster/horn stack, and automatically adjust to its startup characteristics.
One such result is the absorption of microwave power by the ferromagnet when the microwave frequency matches the resonance frequency.
