A rigorous new electromagnetic theory has been developed to compute the speckle pattern of 2D random microrough surfaces with perfect conductivity, when the width of the irregularities is less than 10 um. The computer code enables us to compute rigorously the speckle pattern, whatever the number of irregularities illuminated by the laser beam. Our first numerical results are compared with some predictions of the speckle theory developed in optics.
