摘要：

The transport of electromagnetic energy along structures consisting of arrays of closely spaced metal rods (spacing=0.2 cm) was investigated in the microwave regime at 8.0 GHz (lambda =3.7 cm). The dispersion relation shows that information transport occurs at a group velocity of 0.6c. The electromagnetic energy is highly confined to the arrays (90% within a distance of 0.05 lambda from the array). The propagation loss in a straight array is 3 dB/8 cm. Routing of energy around 90 degrees corners is possible with a power loss of 3-4 dB. Analogies to plasmon wires consisting of arrays of nm-size metal clusters are discussed.
