✦ Synopsis

From theory it is predicted that Lamb modes having a positive group velocity and those having a negative group velocity correspond to, respectively, negative and positive peaks on a spectrum showing the angular derivative of the phase of the transmission coefficient of the elastic plate. Experimental data are presented here that support this prediction.
