A Split Ring Resonator Dielectric Probe for Near-Field Dielectric Imaging
Abstract A single split-ring resonator (SRR) probe for 2D surface mapping and imaging of relative dielectric permittivity for the characterisation of composite materials has been developed. The imaging principle, the analysis and the sensitivity of the SRR surface dielectric probe data is described....
