Numerical and experimental study explores the effect of constriction shape on band-gap width in artificial crystals, suggesting implications for metamaterial design.
It has been demonstrated - both numerically and experimentally - that constrictions arising in artificial crystals composed of touching impermeable inclusions can strongly inhibit the propagation of scalar waves, giving rise to wide complete band gaps. Building on this, we study the influence of the inclusion shape on the gap width when the contact points are preserved across different lattice types. The analysis reveals that the constriction geometry plays a decisive role in governing wave propagation; in effect, it acts as a tuning parameter for maximizing the band-gap width. Our findings may be taken into account for the design of future metamaterials.
