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

Huang, Da; Poutrina, Ekaterina; Smith, David (AMER INST PHYSICS, 2010)

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, Stephane; Rose, Alec; Poutrina, Ekaterina; Huang, Da; Smith, David (AMER INST PHYSICS, 2010)

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 ...
Nonlinear oscillator metamaterial model: numerical and experimental verification

Poutrina, Ekaterina; Huang, D; Urzhumov, Yaroslav A.; Smith, David R. (Optics 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 ...
Nonlinear parameter retrieval from three- and four-wave mixing in metamaterials

Rose, Alec; Larouche, Stephane; Huang, Da; Poutrina, Ekaterina; Smith, David (AMER PHYSICAL SOC, 2010)

We present a generalized nonlinear susceptibility retrieval method for metamaterials based on transfer matrices and valid in the nondepleted pump approximation. We construct a general formalism to describe the transfer ...
