Evanescent matter-waves produced by an atom wave packet incident onto arepulsive barrier edge can be back-refracted and reconstructed by theapplication of negative-index "comoving" potential pulses. One shows that thosecollapses and revivals of evanescent matter waves give rise to surface matterwaves and should be observable via atom reflection echoes issued from thebarrier interface. This property, together with the property of inducingnegative refraction, makes such potentials the matter-wave counterpart ofnegative-index materials in light optics.
