Electromagnetic-acoustic conversion — a result of the action of a surface forceKapitza Institute of Physical Problems, Russian Academy of Sciences, ul. Kosygina 2, Moscow, 117334, Russian Federation The physical interactions responsible for generation of acoustic waves in a conductor whose surface is exposed to electromagnetic radiation is analyzed. It is shown that the main features of the inertial, induction, and deformation mechanisms of electromagnetic—acoustic conversion can be obtained by assuming that the excitation force is of a purely surface character. Current experimental investigations in this field are reviewed.
