Raw TE moulds, TM moulds, the higher mode and cavity 5 corresponding frequency of higher mode of itself is all far above the frequency of foregoing first mode
Rate can be filtered by low-pass filter.
It will illustrate the advantage of the resonator of the present invention by specific experiment data below.There is pure ceramic dielectric with one
The single-chamber resonator of harmonic oscillator is comparative example, which is square column type, and the ceramic dielectric harmonic oscillator is using cylindrical micro-
Ripple media ceramic, size is outer diameter 24mm, internal diameter 8mm, high 19mm, and internal diameter corresponds to through hole, and experiment measures humorous with the medium
The resonant frequency of the resonator of oscillator is 1.642GHz, and the mean power of the resonator is 275W.
Using identical cavity and dielectric resonance（Medium of the above-mentioned pure ceramic dielectric harmonic oscillator as harmonic oscillator in this example
Body）, and in the through hole of the harmonic oscillator（Shrinkage pool i.e. in this example）Plate silver（Conductive layer i.e. in this example）, experiment, which measures, to be had
The resonant frequency of the resonator of the harmonic oscillator is down to 0.875GHz, mean power 335W.
It can be seen that harmonic oscillator using the present invention, compared with simple dielectric resonance, can reduce resonant frequency about
800MHz is substantially the half of original resonant frequency, accordingly it is meant that when preparing the resonator of identical resonance frequency, chamber
Body volume will significantly reduce, and the influence to power is little.
And identical cavity is used, dielectric resonance is changed to the identical metal harmonic oscillator of shape, volume, experiment measures
The resonant frequency of resonator with the metal harmonic oscillator is 1.569GHz, mean power 54W.
It can be seen that harmonic oscillator using the present invention, compared with simple metal harmonic oscillator, remains to provide substantially similar
Resonant frequency, and mean power then substantially increases.
In summary, it is known that harmonic oscillator using the present invention has the advantages that the resistance to high-power of dielectric resonance, simultaneously
Have concurrently metal harmonic oscillator resonant frequency it is low, small the advantages of, resonator, the filtering device of the prior art can be widened significantly

The electric field of first mode is circumferentially radially outer along harmonic oscillator, and circumferentially to surround, the frequency of this pattern is low, can use in magnetic field
Make the band connection frequency of wave filter.TE moulds, TM moulds, higher mode and cavity 5 higher mode of itself that medium body 1 generates are all from the
The frequency of one pattern farther out, can be filtered by low-pass filter.
And then the present invention also protects a kind of electromagnetic wave device with above-mentioned filtering device, which can be
Any one needs to use the equipment of filtering device, such as aircraft, radar, base station, satellite etc..These electromagnetic wave devices can receive
