Comparative analysis of edge- and broadside- coupled split ring resonators for metamaterial design - theory and experiments
TLDR
In this article, a quasi-analytical and self-consistent model was developed to compute the polarizabilities of split ring resonators (SRRs) and an experimental setup was also proposed for measuring the magnetic polarizability of these structures.Abstract:
This paper develops a quasi-analytical and self-consistent model to compute the polarizabilities of split ring resonators (SRRs). An experimental setup is also proposed for measuring the magnetic polarizability of these structures. Experimental data are provided and compared with theoretical results computed following the proposed model. By using a local field approach, the model is applied to the obtaining of the dispersion characteristics of discrete negative magnetic permeability and left-handed metamaterials. Two types of SRRs, namely, the so-called edge coupled- and broadside coupled- SRRs, have been considered. A comparative analysis of these two structures has been carried out in connection with their suitability for the design of metamaterials. Advantages and disadvantages of both structures are discussed.read more
