Extraction of constitutive relation tensor parameters of SRR structures using transmission line theory

In this paper, the transmission line theory is utilized to characterize the. metamaterials comprising of microscopic elements of a periodic array, specifically, the traditional split-ring resonators (SRRs), as an example. The. bianisotropic property of the metamaterials is characterized in a, new way different from the existing wave methods. As evident from both simulations and experiments, the SRR array is found to be quite lossy even though it is made of very good conductor or even perfect conductor as in simulation. With the present characterization, we are able to explain physically very well oil how or why the energy gets lost in this structure. Finally, the theoretical result is compared with numerical simulation data olDtained IDased oil quasi-static Lorentz theory to further verily our analysis.
