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 ...
Controlling the Second Harmonic in a Phase-Matched Negative-Index Metamaterial

Rose, Alec; Huang, Da; Smith, David (American Physical Society, 2011-08-01)

Nonlinear metamaterials have been predicted to support new and exciting domains in the manipulation of light, including novel phase-matching schemes for wave mixing. Most notable is the so-called nonlinear-optical mirror, ...
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 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 ...
