    "abstract": "We consider the lateral shift of a light beam reflecting from a dielectric\nslab backed by a metal. It is found that the lateral shift of the reflected\nbeam can be negative while the intensity of reflected beam is almost equal to\nthe incident one under a certain condition. The explanation for the negativity\nof the lateral shift is given in terms of the interference of the reflected\nwaves from the two interfaces. It is also shown that the lateral shift can be\nenhanced or suppressed under some other conditions. The numerical calculation\non the lateral shift for a realistic Gaussian-shaped beam confirms our\ntheoretical prediction.",
