Engineering Physics Annotation << Back Light pressure and panderamotor forces in the very strong fields of radiation Makarov V.P. Rukhadze A.A. Microscopic theory of average forces acting on medium in the very strong fields of electromagnetic radiation, based on the equations of particles motion, is presented. Such forces are: the pressure caused by reflection of radiation from surface of medium, or by scattering of radiation on the particles and panderomator force caused by inhomogenuity of amplitude of radiation in medium. In the weak nonrelativistic fields all these forces increase when increases intensity of radiation. In the strong relativistic fields the pressure on surface of medium also increases, whereas the panderomator force saturated and don’t depends on the intensity of radiation. At the same time the pressure on particles cause by scattering of radiation reaches the maximal value and then decreases quickly when the intensity of radiation increase. Key words: light pressure, pressure at reflection, pressure at scattering, panderomator force. Contacts: E-mail: rukh@fpl.gpi.ru Pp. 24-30.
