Abstract
A noncontact resonameter includes: a resonator to: produce an excitation signal including a field; subject a sample to the excitation signal; produce a first resonator signal in a presence of the sample and the excitation signal, the first resonator signal including: a first quality factor of the resonator; a first resonance frequency of the resonator; or a combination thereof, the first resonator signal occurring in an absence of contact between the sample and the resonator; and produce a second resonator signal in a presence of the excitation signal and an absence of the sample, the second resonator signal including: a second quality factor of the resonator; a second resonance frequency of the resonator; or a combination thereof; a circuit in electrical communication with the resonator to receive the first resonator signal and the second resonator signal; and a continuous feeder to: provide the sample proximate to the resonator; dispose the sample intermediately in the field of the excitation signal during production of the first resonator signal; remove the sample from the resonator; and manipulate a position of the sample relative to the resonator in a continuous motion and in an absence of contact between the sample and the resonator.
