- The self-refraction of some beams in a Newtonian fluid is theoretically studied. Asingle pulse that takes the shape of an isosceles triangle at a transducer and a solitary shockwave are considered as examples. The novelty lies in the consideration of a quasi-stationaryshock wave (with positive or negative pressure) and negative triangular pulses. We concludethat waveforms with negative excess pressure undergo self-focusing, in contrast to those withpositive excess pressure. The difference in self-refraction of quasi-stationary and impulse beamsis revealed by means of numerical modeling.
