Numerical simulation of the problem on electromagnetic and acoustic wave transformation in metals in magnetic field

Mathematical modeling of the problem on transformation of an electromagnetic wave into an acoustic one in alkaline metals in the magnetic field perpendicular to the sample surface has been carried out. Two model of specular and diffuse reflection of electrons are considered. The ultrasonic amplitude on the sample surface and the amplitude of the passed signal are determined with the various parameters; magnitudes of the external magntic field, probable constant of the electron-phonon interaction and ultrasonic wavelength to electron free-path length ratio are calculated. The results of numerical modeling are shown by plots clearly demonstrating in what regions of the parameter changing of the problem the induction of deformation mechanism of the ultrasonic generation becomes dominant. Short description of the programm is given here as well
