“…A thin cylinder intro duced into the high primary mode electrical field region of an open loop resonator induces the sweep of the resonance frequency of the latter and additional losses. Relying [11,12], the ratio of the broadening of the resonance curve of a resonator to the resonance frequency shift can be written as (1) where R and X are the active and reactive components of the complex per unit length resistance of a thin cylinder with a radius r 0 at a frequency f, k 1 is the free space wavenumber, μ 0 is the magnetic constant, and γ is the Euler constant. For high impedance conductors, the frequency sweep of an open loop resonator is much lower than the resonance curve broadening and can be neglected in practice.…”

A transducer of ultra thin conductor parameters on the basis of a superhigh frequency open loop resonator is considered. The conditions for attaining the maximum sensitivity of such a transducer were found by analyzing the spectral characteristics of a resonator with a conductor. A scheme for creating these conditions in a device for the noncontact nondestructive radio wave reso nance diagnostics of the parameters of a glass coated cast microwire that was manufactured using the Ulitovsky-Taylor technology was proposed. The results of testing the working device model for long term stability and the ability to detect small local inhomogeneities and slow microwire parameter drifts are given. The device was shown to have much better characteristics in comparison with the known devices.
