Abstract :
A theoretical evaluation of the possibility of insonation of objects in the frequency range 0.8-2.7 MHz with radiation power density not less than 0.05 W/cm2 by use of one piezoceramic plate converter is considered. An analytical model for estimation of insonation intensity for frequencies close to and far from the resonance frequency of the converter with and without a transition medium between the plate and the object is obtained
