resonator
n 1: a hollow chamber whose dimensions allow the resonant
oscillation of electromagnetic or acoustic waves [synonym:
{resonator}, {cavity resonator}, {resonating chamber}]
2: an electrical circuit that combines capacitance and
inductance in such a way that a periodic electric oscillation
will reach maximum amplitude [synonym: {resonator}, {resonant
circuit}]
3: any system that resonates

Resonator \Res"o*na`tor\ (-n?`t?r), n. [NL. & G.]
1. (Acoustics) Anything which resounds; specifically, a
vessel in the form of a cylinder open at one end, or a
hollow ball of brass with two apertures, so contrived as
to greatly intensify a musical tone by its resonance. It
is used for the study and analysis of complex sounds.
[1913 Webster]

2. Anything that resounds or resonates; specif.:
(a) (Teleg.) An open box for containing a sounder and
designed to concentrate and amplify the sound.
(b) (Elec.) Any of various apparatus for exhibiting or
utilizing the effects of resonance in connection with
open circuits, as a device having an oscillating
circuit which includes a helix of bare copper wire, a
variable number of coils of which can be connected in
circuit with a condenser and spark gap excited with an
induction coil. It is used to create high-frequency
electric brush discharges.
(c) (Wireless Teleg.) The antenna system and other
high-frequency circuits of a receiving apparatus.
[Webster 1913 Suppl.]

  • Resonator - an overview | ScienceDirect Topics
    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 From: Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2014
  • Resonator - an overview | ScienceDirect Topics
    A resonator is generally a structure that confines electromagnetic energy either inside a block of dielectric material, inside a section of metallic waveguide enclosure (Figure 7 25), or between the open or shorted ends of a piece of planar transmission line (i e , microstrip, Figure 7 27) A combination of these may also be used as a resonator
