Analysis of the power dependent tuning of a varactor-loaded metamaterial at microwave frequencies
Abstract
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 of power, a VLSRR medium can be described
by its second and third order nonlinear susceptibilities, making it a useful analog
medium for the quantitative investigation of other nonlinear phenomena that might
be achieved using inherently nonlinear materials integrated into metamaterials. Experimental
measurements of the resonance frequency shift with power from fabricated VLSRR samples
are found to be in excellent agreement with the analytical model. © 2010 American
