Abstract

We consider a simplified model for a nonlinear magnetic metamaterial, consisting of a split-ring resonator (SRR) array capable of nonlinear capacitive response. We compute the localized modes around simple magnetoinductive impurities located at the bulk of the array, in closed form for both, linear and nonlinear cases. We also examine the scattering of magnetoinductive waves across internal (external) capacitive (inductive) defects coupled to the SRR array, and examine the ocurrence of Fano resonances, and how to tune them by changing the external parameters of the system. Finally, we describe a method for building a stable localized magnetoinductive mode embedded in the continous band of extended states.
