... Phase Conjugation of Nonlinear Acoustic Waves in Piezosemiconductors . ... The real time acoustic waves phase conjugation (WPC), based on the self-consistent physical mechanisms, was realized up to present time only for the monochromatic waves [1]. ... WPC of nonlinear acoustic waves in this case can be realized due to electron's density modulation provided by the train of short light impulses pumping the sample. ...
... Phase of Shock Wave Harmonics in Focused and Unfocused Ultrasonic Sound Beams . ... We present experimental results from 2 plane and 2 focusing sound sources with frequencies near 1 MHz in water. ... For plane sources: after small fluctuations within the nearfield the phase parameter flattens out at a value near -pi/2, reaching a slightly more negative value with higher source amplitudes. ... They are more sensitive to the source amplitude than with the plane sources. ...
... Phenomenon of Prebifurcation Noise Enhancement: Linear and Nonlinear Analysis . ... The phenomenon of prebifurcation noise enhancement in nonlinear systems with the period doubling bifurcation is studied. ... Intensity of fluctuations is estimated both for linear regime (far from bifurcation threshold) and for nonlinear regime (in the vicinity of bifurcation threshold). ...
