Title: Microwave Conductance of Semicontinuous Metallic Films from Coplanar Waveguide Scattering Parameters
Published: May 06, 2013
Abstract: Conductance of thin semicontinuous metallic films is measured in coplanar waveguide configuration at frequencies of 100 MHz to 20 GHz. The presented model of the microwave network correlates the experimental scattering parameters (S11) and (S21) with complex impedance and propagation constant from which we determine the films surface conductance, coefficient of reflectance and transmittance. The measurement is illustrated on films of gold, 4 nm to 12 nm thick, which after percolation from individual nanoparticles resemble a continuous conductor. The presented methodology accurately captures the insulator to conductor transition, and can be used to determine microwave characteristics of such materials.
