摘要：

The paper presents a methodology for the modeling of metamaterial structures which are built as lattices of double negative unit cells. The effective description for a double negative unit cell is found by parameter fitting of dispersive models. The obtained models are implemented in higher level simulations and used for the characterization of large metamaterial macrostructures, A parabolic antenna composed of split ring resonators and wires is anylyzed by this approach, and its radiation and refraction behavior is evaluated. The simulation results for the detailed and effective representations of the antenna are compared to each other and validate the proposed modeling approach.
