Abstract: In this paper, modulation of reflected wavefront out of the incident plane by a tunable acoustic metasurface is investigated based on the fully generalized Snell’s law in the three-dimensional space. The metasurface is constructed by… read more here.

Abstract: A bifunctional reconfigurable phase-modulated metasurface for manipulating reflected waves is proposed. Each constituent element incorporates a varactor diode, and the reflection response of the unit cell can be tuned through feeding different bias voltages. Thus,… read more here.

DOI: 10.1785/0120200156
Abstract: The autocorrelation of ambient noise is used to capture reflected waves for crustal and sedimentary structures. We applied autocorrelation to strong-motion records to capture the reflected waves from sedimentary layers and used them for tuning… read more here.
