The system consists of an enclosed waveguide operating in the fundamental mode, with an array of microphones and data processing electronics for determining the complex reflection coefficient of a surface two meters square.
An algorithm is described in which galvanostatic regulation of electrochemical impedance measurements is conducted with an amplitude of current perturbation that is adjusted at each frequency to yield a desired variation in potential. Measurements at previous frequencies are used to estimate the val
temperatures. At the same time such an oscillator has a number of advantages-simple tuning, small size and weight, long running time with high frequency stability after siphoning helium 4, s -and is convenient to use. We should note that thanks to the low noise and high frequency stability, there w
