WebDec 15, 2024 · Phononic crystals (PCs) have attracted increased attention over the last two decades due to their unique physical properties. These properties include phononic band gaps (BGs) where the propagation of elastic waves is forbidden [ [1], [2], [3]]. Bragg scattering and local resonance are two main mechanisms that lead to BG formation.
