Abstract
The frequency response of a diffusion transducer with gauze electrodes, studied theoretically at high frequencies, is proportional to ∼ω-3/2 starting with ω = D/R 2 at ω < ν/R 2 and to ∼ω-1 at ω > ν/R 2. Here, ω = 2πf, f is the signal frequency, ν the electrolyte viscosity, D a diffusion coefficient, and R the radius of the gauze filaments. The calculation is compared with experiment.
