Accordingly, the averaged characteristics are obtained for an ensemble of metal nanoparticles with regard for the influence of the nanoparticle shape on the depolarization coefficients and the components of the optical conductivity tensor. Three original variants of the nanoparticle shape distribution function are proposed on the basis of the joint application of the Gauss and “cap” functions. |
