Si. Konovalov et Ag. Kuzmenko, DIRECTIVITY OF A PULSED PIEZOELECTRIC DISK WITH A DAMPER, Russian journal of nondestructive testing, 30(4), 1994, pp. 295-299
The particle-velocity pulse on the radiating surface of a piezoelectri
c disk is calculated from the specified voltage pulse. The directivity
patterns are calculated numerically and analyzed by a spectral method
. It is shown that the directivity depends only slightly on the wave i
mpedance of the damper.
