Abstract
Second-harmonic near-field optical images of nonlinear nano- objects placed at the surface of a substrate are calculated for different polarization configurations by making use of a new approach to solution of macroscopic self-consistent field equation of Lippmann-Schwinger type. Numerical simulations are carried out for the case of illumination with a linearly polarized Gaussian beam. It is found that the appearance of second-harmonic images can be used to deduce the symmetry of the nonlinear susceptibility tensor of the object and that of the substrate.
