Ev. Ivanov et Yv. Sudenkov, ANALYSIS OF THE FOCUSING EFFICIENCY OF PULSED PRESSURE WAVES AS A FUNCTION OF THE INITIAL AMPLITUDE DISTRIBUTION AND TEMPORAL PROFILE, Technical physics, 43(7), 1998, pp. 855-858
Solutions of the parabolic diffraction equation for the focusing of pr
essure pulses with a monopolar or bipolar initial profile and a bell-s
haped or annular amplitude distribution presented. These results are a
nalyzed and conditions determined under which more efficient focusing
occurs during the transition from a bell-shaped to an annular distribu
tion of the initial amplitude, as well as when a monopolar pulse is re
placed by a bipolar pulse. (C) 1998 American Institute of Physics. [S1
