Abstract
We present experimental results of the transmission coefficient of a metamaterial slab and the effect of the metamaterial on the radiation pattern of an antenna placed near the slab in the frequency range close to the plasma frequency of the slab. The metamaterial focuses the radiation from the patch antenna within a narrow cone close to the slab's normal. We give a new simple explanation of the focusing effect based on the index of refraction of the metamaterial being less than one and the attenuation of electromagnetic waves within the metamaterial slab.
