Abstract : Document describes a piezoelectric tubular monopole element with zero end displacement which has an omnidirectional sensitivity over the widest possible frequency range. The center section is radially or thickness-poled and the end sections are longitudinally or length-poled. The positive electrodes are connected in parallel and the negative electrodes are connected in parallel for electrical parallel output. (Author)
