A three-dimensional left-handed metamaterial based on the rotated TLM method

In this contribution a three-dimensional left-handed metamaterial is presented which is shown to be a physical implementation of the rotated TLM scheme. The key characteristics of the metamaterial in terms of dispersion relation and Bloch impedance as well as composite right/left-handed response are analysed. An implementation of the 3D metamaterial is presented and measurements provided showing very good agreement. Different computational approaches to the analysis of the structure aperiodic arrangements are discussed.     «
