• The physical model of photoinduced mass transport, which was previously proposed, was improved. A novel numerical method was developed to analyze electromagnetic field distribution and energy transformation in more detail. The electromagnetic field was calculated using a modified cubic interpolated propagation/constrained interpolation profile (CIP) method. The mass transport was calculated using a particle method proposed previously. The photoinduced surface relief of an azobenzene polymer film formed by optical near-field exposure was simulated using a proposed physical model and a numerical method. The numerical results were compared with experimental results. The surface profile and energy dependence of thne photoinduced surface relief formation obtained numerically were coincided with the experimetal results.
