Analysis of the power dependent tuning of a varactor-loaded metamaterial at microwave frequencies

Huang, D; Poutrina, E; Smith, DR (Applied Physics Letters, 2010-03-26)

We present an analysis of the nonlinear, power-dependent resonance frequency shift for two metamaterial mediums consisting of arrays of varactor-loaded split ring resonators (VLSRRs). We confirm that, over a limited range ...

Experimental determination of the quadratic nonlinear magnetic susceptibility of a varactor-loaded split ring resonator metamaterial

Larouche, S; Rose, A; Poutrina, E; Huang, D; Smith, DR (Applied Physics Letters, 2010-07-05)

This letter presents a quantitative measurement of the second harmonic generated by a slab of varactor loaded split ring resonator metamaterial and the retrieval of the effective quadratic nonlinear magnetic susceptibility ...

Magnetic superlens-enhanced inductive coupling for wireless power transfer

Huang, D; Urzhumov, Y; Smith, DR; Hoo Teo, K; Zhang, J (Journal of Applied Physics, 2012-03-15)

We investigate numerically the use of a negative-permeability perfect lens for enhancing wireless power transfer between two current carrying coils. The negative permeability slab serves to focus the flux generated in the ...

Nonlinear oscillator metamaterial model: numerical and experimental verification.

Poutrina, E; Huang, D; Urzhumov, Y; Smith, DR (Opt Express, 2011-04-25)

We verify numerically and experimentally the accuracy of an analytical model used to derive the effective nonlinear susceptibilities of a varactor-loaded split ring resonator (VLSRR) magnetic medium. For the numerical validation, ...
