Abstract :
The characteristics of the propagating waves on an array of identical wires have been measured. Experimental data showed that propagating waves could be supported on the structure without significant attenuation for two frequency bands. The central frequency of the higher passband was about 3 times higher than that of the lower passband. All propagating waves were slow waves. Phase velocities were varied from 0.99 to 0.25 of the free-space velocity. The 
diagram of the waves were obtained and were found in good agreement with the theory.
