On the Possibilities of Controlling the Dynamic Properties of Cylindrical Piezoceramic Radiators in Telecommunication Problems

Possibilities of Controlling the Dynamic Properties of a Cylindrical Piezoceramic Acousto-electronic Device with Two-frequency Resonance Excitation

“…The established dynamic properties of the acoustoelectronic device with two-frequency resonance excitation have a clear physical justification. It is based on the connection of electric, mechanical and acoustic fields during energy conversion in piezoceramic media, the connection of the device external and internal shells acoustic fields during an acoustic field forming in the space between shells due to multiple exchange of acoustic waves among them and the connection of the energy conversion processes and its formation in the acoustic field [2,3,5,11,12]. The feature of the electromechanoacoustic energy conversion in the device under consideration is that all three fields of each piezoceramic shell have radial symmetry.…”

“…Acoustoelectronic systems with dynamic control of their parameters are becoming increasingly important when creating modern echolocation multifunctional devices [1][2][3].…”

“…These connections are based on electrical elasticity of piezoceramic transducers and multiple exchanges of radiated and reflected sound waves in systems [2,3,5,[8][9][10][11][12] between their elements.…”

“…In work [5], the dynamic properties of the output parameters of the device under consideration at identical resonance frequencies of its piezoceramic shells, thicknesses and media filling them were studied. The results of work [3] made it possible to establish abrupt changes in the given type of acoustoelectronic devices potential dynamic properties at the same resonance frequencies of shells and filling media, but different relative thickness of shells.…”
