Abstract
Our research presents theoretical, numerical and experimental investigations of asymmetric elastic-wave transmission in a thin plate with a lossless elastic metasurface. A theoretical framework is developed to control the asymmetric elastic-wave transmission without tailoring losses. We numerically and experimentally demonstrate that the asymmetric wave behavior can be realized on basis of the higher order diffraction in a lossless structural waveguide. We further experimentally show that the novel phenomenon can be obtained within a relatively broad range of incident angles and frequency band.
