On the theory of self-action of ultrasonic and hypersonic waves

The self‐action of ultrasonic and hypersonic waves in a homogeneous medium is investigated. It is proved, that the mathematical technique used for the description of the self‐focusing of laser beams is applicable to the treatment of thermal self‐focusing (self‐defocusing) of sound waves including th...
