• The lateral energy distribution and the lateral decay length of the shear horizontal wave (SH wave) at 5.6 MHz are investigated experimentally by using a waveguide for the SH wave made by evaporating a conductive Al film onto a PZT ceramic plate polarized parallel to its surface. Experimental results are well explained by a simplified theory along the same line as Tiersten's. The propagation loss of the guided SH wave is 0.18 dB/μsec. Moreover it is shown that the Bleustein-Gulyaev wave which corresponds to the zeroth-order SH wave in the case of an infinitely thick plate can be guided by a conductive film. A circular waveguide of diameter 40 mm prepared on a PZT disk of thickness 0.25 mm, polarized radially and parallel to the surface, has a delay time 53 μsec and an insertion loss 39.7 dB.
