Abstract :
We investigate the complex conductivity of silver nanowire thin films using terahertz time-domain spectroscopy. The measured conductivity shows a characteristic non-Drude response unlike bulk metals. The interesting behavior is explained by the Gans approximation and the Drude-Smith model.
