Motivated by the need for a modeling tool for nanostructures interacting with a substrate and an AFM probe, we developed a MATLAB implementation of the discrete dipole approximation with surface interactions (DDA-SI). The method is applied to investigate the near-field coupling between particles on the surface and an AFM probe. The results presented here explore the effects of a number of physical, geometrical and material properties that can eventually assist nanolithography, particularly in defining the parameters for nano-writing.
