Abstract
A flexural wave absorber includes a metasurface with an inner portion, an outer portion, and a plurality of beam strips extending between the inner portion and the outer portion. The metasurface also includes a plurality of coupled resonators disposed on the plurality of beam strips. The plurality of coupled resonators can include a lossy resonator and a lossless resonator, two lossy resonators and a lossless resonator, or a lossy resonator and two lossless resonators. In addition, each of the plurality of beam strips can have multiple pairs of coupled resonators disposed thereon that work at or absorb different frequency ranges.
