| description | Acoustic wave reflections from corrugated surfaces are analyzed. For this work, a proposal of Yi-Fan Zhu on a relatively simple model of metasurface is taken as a basis. Each groove of a corrugated surface can be considered analogous to a linear array, while the depth of its grooves is related to the phase of each source. Zhu's original proposal takes the phase gradient of the arrangement as a design parameter. In this paper we analyze the advantages of surface design from the time-delay gradient. It also presents the possibility of impose brief delays in the whole pattern of reflections independently of the general design process. |
