The authors show how a flat slab made of a metamaterial engineered to have a small negative index of refraction can be used to reshape radiation emitted from an isotropic source and produce a highly directional output beam. The slab makes a filtering of high transverse wave vectors of the input diverging beam. The predicted phenomenon is demonstrated at microwave frequencies using a two-dimensional photonic crystal made of alumina rods. Simulations using the finite-difference time-domain method support the experiments.
