Abstract

The cross section of the electric dipole absorption of a small conducting cylindrical particle located in the field of a plane electromagnetic wave is calculated in terms of the classical kinetic theory of electrical conductivity. The boundary conditions of the nonequilibrium charge-carrier distribution function are specified using the Soffer model taking into account the dependence of the specular reflectance on the surfaceroughness parameter and the angle of electron (hole) incidence on the particle’s internal surface. The results of calculating the cross sections of the electromagnetic-radiation absorption of metal and semiconductor particles are presented. The obtained results are compared with theoretical calculations for the model of diffusespecular Fuchs boundary conditions.
