RADIATION IMPEDANCE OF PIEZOELECTRIC CYLINDERS OF THE TRANSDUCER WAVEGUIDE TYPE AT RADIATION BY IT IN THE SEMI-INFINITE SPACES

For water filled coaxially located piezoelectric cylinders with the phased excitation as the running wave, forming the transducer of waveguide type, radiating in semi-infinite spaces, results of calculations of frequency characteristics of own, mutual and full radiation impedance are resulted and analyzed. Influence on these characteristics, and also – on frequency dependences of amplitudes of exciting electric pressure, the waves reflected from face-to-face and back apertures of the transducer of waveguide type is shown.
