Potentially achievable dynamic properties of an acoustoelectronic device with single-frequency resonant excitation in the form of a coaxial system formed from two cylindrical piezoceramic shells and a liquid layer between them, depending on the physical characteristics of this liquid, are investigated. By the method of numerical analysis, on the example of acoustic fields, the peculiarities of the behavior of potentially possible dynamic properties of such devices for the options of their construction with filling with liquids with different density and speed of sound in them are established. The peculiarities of the influence of the physical characteristics of the liquids that fill the device on the potentially possible dynamic properties of acoustoelectronic devices of this type are studied. It is shown that these features consist in the formation of two resonance regions, which differ significantly in the central frequencies, the resonant frequency bands and the maximum pressure amplitudes in them. Filling devices with light liquids causes a decrease in the values of the central frequency of the resonance regions and the frequency interval of small pressure amplitudes between the two resonance regions. Filling devices with heavy liquids is characterized by the opposite effect. The influence on the established potentially possible dynamic properties of such devices is analyzed by introducing operational control methods into them from the electrical side. The physical reasons for the emergence of the established dynamic properties are stated.
