Accurate Analysis of Metamaterials Involving Finite Arrays of Split-ring Resonators and Thin Wires

Abstract — In order to gain physical insight into how some metamaterial structures behave, we report our results obtained by accurate numerical solutions of electromagnetic problems related to various constructions of split-ring-resonators (SRRs) and thin wires (TWs). Single and multiple layers of arrays of SRRs and TWs are investigated in detail using the electric-field integral equation. Without utilizing any homogenization techniques, we accurately model large numbers of unit cells that translate into very large computational problems, which are solved efficiently by employing multilevel fast multipole algorithm. 1
