摘要
We experimentally show coherent, enhanced terahertz transmission through dense 3D random metallic media having subwavelength heterogeneity. Preservation of the incident polarization state and strong dispersion of the transmitted radiation indicate that the enhanced transmission is due to delocalized plasmonic propagation over distances 5 orders of magnitude greater than the skin depth. The experimental observations are supported by numerical finite difference time-domain simulations.
