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.

  13. Dispersion relations have been calculated using a complex photonic bandstructure method described in [11], and finite difference time domain software OMNISIM© has been employed to simulate the beam propagation. Due to minor convergence problems the frequency scales for the two methods are slightly different. In order to provide matching of the two scales, the bandstructure has been renormalized to provide matching of the frequencies at the J point which can be determined for both calculation techniques.
