Coupled resonator acoustic waveguides-based acoustic interferometers designed within two-dimensional phononic crystals: experiment and theory
David Martínez-Esquivel, Rafael Alberto Méndez-Sánchez, Hyeonu Heo +4
The acoustic response of defect-based acoustic interferometer-like designs, known as Coupled Resonator Acoustic Waveguides (CRAWs), in two-dimensional phononic crystals (PnCs) is r…

Multifunctional acoustic device based on phononic crystal with independently controlled asymmetric rotating rods
Hyeonu Heo, Arkadii Krokhin, Arup Neogi +5
A reconfigurable phononic crystal (PnC) is proposed where elastic properties can be modulated by rotation of asymmetric solid scatterers immersed in water. The scatterers are metal…
