Acoustic traveling wave tube system and method for forming and propagating acoustic waves
Abstract:
The present invention is an acoustic traveling wave tube system for propagating a directional acoustic wave comprising an acoustic traveling wave tube having a cylindrical shape with a load on one end of the tube, a plurality of excitation rings positioned around a circumference of the tube and spaced at predetermined intervals along a length of the tube and a microprocessor having a database containing a plurality of waveforms representative of acoustic signals. The microprocessor energizes one of the plurality of excitation rings to form an acoustic wave, sequentially energizes one or more of the remaining excitation rings along the length of the tube to amplify the acoustic wave as the acoustic wave travels along the length of the tube, and propagates the acoustic wave from an end of the tube opposite the load as a shaped directional acoustic wave.
