Electromagnetic Modeling of Split-Ring Resonators [PDF]
2006 European Microwave Conference, 2006 In this paper, we report our efforts to model split-ring resonators (SRRs) and their large arrays accurately and efficiently in a sophisticated simulation environment based on recent advances in the computational electromagnetics. The resulting linear system obtained from the simultaneous discretization of the geometry and Maxwell's equations is solved
