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. Se analizan las reflexiones de ondas acústicas en superficies corrugadas. Para este trabajo se toma como base una propuesta de Yi-Fan Zhu sobre un modelo relativamente sencillo de metasuperficie. Cada ranura de una superficie corrugada puede considerarse análoga a una fuente de un arreglo lineal, mientras que la profundidad de sus hendiduras se relaciona con la fase de cada fuente.  La propuesta original de Zhu toma como parámetro de diseño al gradiente de fase del arreglo. En este trabajo se analizan las ventajas del diseño de superficies a partir del gradiente de retardos temporales. Se presenta además la posibilidad de incorporar breves retardos en todo el patrón de reflexiones de modo independiente al proceso general de diseño. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/73 10.37537/rev.elektron.3.1.73.2019 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/73/66 https://elektron.fi.uba.ar/elektron/article/view/73/108 Derechos de autor 2019 Georgina Alejandra Lizaso Elektron Journal; Vol. 3 No. 1 (2019); 24-28 Revista Elektron; Vol. 3 Núm. 1 (2019); 24-28 Revista Elektron; v. 3 n. 1 (2019); 24-28 2525-0159 2525-0159 dispersionless reflection acoustic metasurfaces reflection control metasuperficies acústicas control de reflexión reflexión sin dispersión.
