    • The design of a wideband and widebeam piston transducer in a finite closed circular baffle 

      Şahin, Z.; Köymen, Hayrettin (2008-06-07)
      The design of a high power piezoelectric underwater transducer operating at frequency range 40 kHz-80 kHz with acoustic power capability in excess of 250W is described. The transducer consists of two back-toback elements. ...
