Abstract

The present disclosed technique pertains to high Q mode resonators, and, more particularly, to a technique for separating a high Q mode from masking low Q modes. In a first aspect, it includes a high Q mode resonator, comprising: a housing defining a clover-shaped resonating cavity; a dielectric material filling the cavity; an input to the cavity; and an output from the cavity. In a second aspect, it includes a high Q mode resonator, comprising: a housing defining a clover-shaped resonating cavity, the cavity comprising four intersecting right angle, cylindrical chambers; a fluid dielectric material filling the cavity; an input to the cavity; and an output from the cavity. In a third aspect, it includes a method, comprising: introducing a signal to a resonating cavity; resonating the signal within a chamber, the resonating cavity shifting the resonance of the low Q mode higher in frequency than it shifts the high Q mode; and permitting egress of the signal from the resonating cavity. In a fourth aspect, it includes a method for use in designing a high Q mode resonator, comprising: calculating the dimensions of the simple cylindrical cavity for the frequency desired for the high Q mode; and decreasing the outer radius of the simple cylindrical cavity while holding the sum of the inner and outer radius equal to the initial simple cylindrical radius.
