Abstract

We present two novel techniques for modeling two- and three-dimensional metamaterials with negative refractive index by transmission-line matrix (TLM) networks. The TLM networks are numerical models of reactively loaded periodic networks that support backward waves and constitute artificial media with negative refractive index. The TLM models, their implementations, and results computed with the models will be presented.
