摘要：
In this paper, the wave propagation in a grounded dielectric slab with double negative (DNG) metamaterials is studied. Dramatically different evanescent surface modes (electromagnetic fields exponentially decay both in air and inside the slab) are observed. They are highly dependent on medium parameters. An infinite number of complex surface modes are found to be existing which have proper field distribution in the air region. The investigations on the Poynting vectors show that they do not carry away energy in both transverse and longitudinal directions.
