resonator

[′rez·ən‚ād·ər]
(physics)
A device that exhibits resonance at a particular frequency, such as an acoustic resonator or cavity resonator.

Resonator

 

in architecture, a small chamber or vessel placed in the walls and arches of buildings with its aperture toward the interior of the structure. It reinforces sound, acting as an acoustic resonator. A resonator may also be employed as a hollow structural element to lessen the weight of an arch.


Resonator

 

an oscillatory system exhibiting pronounced resonant characteristics. In practice, the term “resonator” is usually applied to an oscillatory system that has distributed parameters, or an infinite number of degrees of freedom. Resonators with elastic oscillations may be strings, diaphragms, acoustic resonators, or rods, for example, the prongs of tuning forks. Electromagnetic resonators may be cavities bounded by conducting walls, systems of mirrors, or crystal plates.

(3) Set the length of the kth resonator to the value of [L.sup.V.sub.k] + [[DELTA].sup.V] (or [L.sup.V.sub.k] - [[DELTA].sup.V]) for the vertical polarization and [L.sup.H.sub.k] + [[DELTA].sup.H] (or [L.sup.H.sub.k] - [[DELTA].sup.H]) for the horizontal polarization (k = 2, 3, ..., N) so that the (k-1)th/kth notch gets removed, that is, different codes can be generated from the optimized all-one code by simply setting two adjacent resonator lengths to be equal.
