Using classical electrodynamics, a theoretical analysis of second and third harmonic generation (SHG and THG) by spherical metal clusters is presented. Based on the anharmonic oscillator model for the displacement of the surface charge, the sources of the radiation generated in second and third harmonic are determined by using the approximation of the second and third power of the linear surface charge. Then the higher harmonic electric fields are determined by matching the electric fields inside and outside the sphere. Angular dependence of the intensities and the degree of polarization are studied. Detailed results of the SHG and THG are presented. The particle size sensitivity of Mie-scattering is increased by nonlinearity.
