The influence of fabrication errors of metallic nanofilm with the grating-like and nonsymmetrical corrugation on one or two sides on surface plasmons resonance is analyzed by using boundary integral method. The scattering cross-section and the near-field intensity distribution of its corresponding resonant wavelengths for the finite grating-like nanostructure with or without fabrication defects are numerical investigated. The results show that the resonant wavelength is influenced by the fabrication flaws. More detailed directions of the electric flux lines around the metallic grating-like nanostructure and the near-field intensity distribution indicate that the excitation of surface electrons is influenced. This investigation will provide useful information for the fabrication of the metallic grating-like nanostructure and the experimental error analysis of the scientists.
