BLOCH IMPEDANCE ANALYSIS FOR A LEFT HANDED TRANSMISSION LINE

Cumali Sabah – Fabio Urbani – Savas Uckun

   In this study, the dispersion relation and the frequency dependence of Bloch impedance in a left handed transmission line (LH-TL) is carried out using the F-matrix formulation and Bloch-Floquet theorem. The artificial LH-TL formed by periodic lumped elements is described and the F-matrix, dispersion relation and the Bloch impedance are formulated according to this description. Numerical results for lossless and lossy LH-TL are presented and discussed.

Keywords: left/right handed, transmission line, Bloch impedance, Floquet theorem
