摘要：

The unique diagnostics of the low frequency waves excited in magnetoplasma was tested on large "Krot" device. Method is based on measuring the resonance curve frequency and amplitude modulation of a tiny double-wire probe caused by plasma density variations. Depending on the operating point position at the probe resonance characteristic we can measure density fluctuations down to delta n/n <= 10(-5). The possibility of harmonic and non-periodic density perturbation measurements is shown in experiments. We also demonstrate the possibility of using the resonator probe as a noninvasive medical tool to diagnose the pathologies and diseases accompanied by changes in tissue complex dielectric coefficient.
