摘要：

Scattering of a two-dimensional, spatially partially coherent electromagnetic field by a two-dimensionally-modulated microstructured medium is treated exactly by means of the coherent-mode representation of the cross-spectral density tenser and a rigorous diffraction theory for fully coherent fields. An explicit method of solution is provided for an isolated groove or slit in a perfectly conducting substrate. The results demonstrate a significant impact of a reduced degree of spatial coherence an the radiant intensity of the field diffracted by such a microstructure. The validity of results obtained on the basis of Kirchhoff's boundary conditions is also assessed.
