Abstract

We report the results of simulations relating to the illumination of a
structure consisting of a slab constructed from a 2-D hexagonal array
of metal rods with a terahertz frequency source. As a consequence of
negative refraction an essentially non-divergent beam pattern is
observed. Although the results presented relate to the terahertz regime
they should also be applicable at other frequencies. (C) 2008 Optical
