摘要：In this paper, a numerical three-dimensional (3D) model of electromagnetic left-handed metamaterials (LH MTM), is presented. The model is developed by using the Transmission Line Matrix (TLM) method based on Z-transforms, extended here to account for dispersive LH MTM properties in the timedomain. The dispersion function is based on the Drude model which allows the description of the electromagnetic properties of metamaterials over a wide frequency range. The accuracy, efficiency and stability of the proposed approach are verified using analytical solutions. In addition, some examples are shown which illustrate the unique characteristics of metamaterials
