Show more >Transmission of acoustic waves through a periodic array of sub-wavelength slits or holes have been studied in several recent works in relation with physical phenomena such as resonant (extraordinary) transmission, broadband sound shielding or acoustic induced transparency (AIT). In this work, we present for the first time the study of analogous phenomena for Lamb waves propagating in a thin plate. We study the transmission through one or two rows of a periodic array constituted by thin bridges separated by rectangular holes. When two rows of such an array are considered, the choice of the distance between both rows allows the realization of a broadband attenuation up to 99% in the transmission. These investigations should have implications for sound isolation, filtering and sensing applications.Show less >
