Dielectric Function of Matrix Disperse Systems with Metallic Inclusions. Acount of Multipole Interaction between Inclusions
RÉSUMÉ
Dielectric function of small density system of fine metallic particles solutes in dielectric matrix, has been calculated. For that purpose, the improved variant of Maxwell-Garnett approach was developed with due account of pair wise multipole interaction between inclusions. An exact solution is given for the electrostatic problem of two metallic spheres polerizability. An accurate account of the pair wise interaction leads to a non-analyticity appearing in the dielectric function, which is the result of summing up all the series of perturbation theory. Singularities of dielectric function connected with this non-analyticity give rise to the origin of new excitation branches in a system.
