WebFeb 1, 2024 · Phononic crystals (PnCs) are periodic elastic structures in 1D, 2D, or 3D configurations that can be used for controlling the mechanical waves. Some special characteristics such as negative refraction, self-collimation (SC), and forbidden band structure enable these structures to show different applications [ [23], [24], [25] ].
Web1 day ago · 1.Introduction. Phononic crystals (PnCs) are artificial metamaterials that constitute a periodically arranged individual in a mixture [1].PnCs were initially studied by Siglas, Economous and Kushwaha et al.
