Analytical solutions for smooth positive-to-negative transition materials
Yi S. Ding, C. T. Chan
We obtain analytical solutions for positive-to-negative transition materials with a smooth transition profile "". The fields are expressed in terms of hypergeometric functio…
Modulational instability of magnetoelastic metamaterials
Yi S. Ding, Ruo-Peng Wang
We study the modulational instability of recently designed magnetoelastic metamaterials composed of elastic-mediated split-ring resonators (SRR). An effective circuit model is deve…
Modulational instability of a recent nonlinear plasmonic metamaterial: Finite-difference-time-domain simulations
Yi S. Ding, Jiasen Zhang, Ruo-Peng Wang
By doing time-domain simulations, we find the proposal for negative-to-positive index switching proposed in [Physical Review Letters, 106 105503 (2012)] may be fragile. The negativ…
Nonlinear magnetic metamaterials and possible applications on all-optical comparers and bistabilities in Fabry-Perot cavities
Yi S. Ding, Ruo-Peng Wang
We investigate the modulational instability and time-domain dynamics of nonlinear magnetic metamaterials composed of coupled split-ring resonators loaded by Kerr nonlinearity. Our…
