Complete mode conversion for elastic waves reflected by elastic metamaterial slab with double hexapole resonances
Di Liu, Wenjie Yu, Qiujiao Du +2
In this study, we investigate the phenomenon of mode conversion in elastic bulk waves using coupled hexapole resonances. A metamaterial slab is proposed enabling the complete conve…
