Abstract :
The surface acoustic wave (SAW) soliton of the Korteweg-de Vries (KdV) type propagating on the metallic grating waveguide has been observed experimentally. The periodic train of 2 solitons developed from the continuous sine wave of the SAW. A large-amplitude soliton caught up with a small amplitude soliton and these two solitons recombined into the initial sine wave at the recurrence point. The observed waveforms agreed with the calculated ones very well which were obtained by solving the KdV equation and satisfied the first conservation law of the KdV equation
