Wave Propagation in Tapered Periodic Curved Meta-Frame Using Floquet Theory
TL;DR: In this paper, the elastic wave propagation and dispersion characteristics of a curved tapered frame structure were investigated analytically, and it was shown that a small periodic bent angle cross-section produces a complete, viz. axial and flexural band gap in the low-frequency region, and conicity enhances the width of the band.
