The diffraction electromagnetic field is calculated by rigorous coupled-wave theory for a binary metallic grating of nanometric dimensions. We discuss in detail the influence of the ratio of grating ridge width to grating period, the depth of groves and the angle of incident wave for the enhancement of diffraction electromagnetic field. Calculations for silver grating and gold grating result in some important conclusions.
