Abstract
We used a broadband, free-space, focused-beam system to measure the transmission and reflection in left-handed-material (LHM) slabs. The samples were made of alternating patterns of copper wires and split-ring resonators on Rogers 5880 substrates separated by Rohacell™ spacers. The measured data show very good agreement with numerical simulations. The measured insertion loss of this structure was at the LHM pass band. Simulations suggest that the loss may be attributable to the finite conductivity of the copper patterns.
