Abstract: It is shown that in an electrokinetic acoustoelectric transducer, when a constant DC electric field (pump voltage) is applied during reception of an acoustic signal, it becomes possible to retransmit the initial external acoustic field. This is due to the presence of simultaneously reverse electrokinetic phenomena in the transducer: electroosmosis and flow potential. The necessary theoretical substantiation of this phenomenon is presented. The data of a full-scale experiment confirming the theory are presented.
Keywords: acoustoelectric conversion, electrokinetic phenomena, current potential, energy pumping, electrokinetic repeater.
