Abstract :
This paper describes the modelling of metamaterials with negative refractive index by means of transmission line matrix (TLM ) networks. The TLM model is based on previously proposed periodic networks that support backward waves and thus represent artificial media with negative refractive index. The TLM model, its implementation, and results computed with this model, will be presented.
