Abstract Based on Fresnel-Kirchhoff theory, the electromagnetic scattering from fractal gratings, which have structure on uniform Cantor sets or Siepinski carpet, is discussed. The scattering intensities of 1-dimensional and 2-dimensional fractal grating with different fractal dimension are calculated and their properties on spatial frequency distrubution are then analysed. The numerical results illustrate the fractal characteristics and frequency selectivities.
