Abstract
Experimental evidence is given for the elliptic backward rotation of particles at the surface of a y‐cut quartz on which elastic surface waves propagate along the x axis. The path of the particle motion is determined by the analysis of the electromotive force induced in a metal‐strip detector in a static magnetic field. The experimental result on the ratio of the major and minor axes of the ellipse is in good agreement with a numerical calculation. The direct measurement of the particle displacement enables one to estimate the power of surface waves. The experiment suggests a possible application of elastic surface waves to a phase shifter in the range of VHF and UHF.Keywords
