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…
Enhanced Instantaneous Elastography in Tissues and Hard Materials Using Bulk Modulus and Density Determined without Externally Applied Material Deformation
Yuqi Jin, Ezekiel Walker, Arkadii Krokhin +3
Ultrasound is a continually developing technology that is broadly used for fast, non-destructive mechanical property detection of hard and soft materials in applications ranging fr…
Nonreciprocal localization of ultrasound in a viscous medium with asymmetric scatterers
Jyotsna Dhillon, Andrey Bozhko, Ezekiel Walker +2
A two-dimensional phononic crystal with asymmetric scatterers is used for the study of Anderson localization of sound along one-dimensional disorder produced by random orientation…
Nonreciprocal transmission of sound in viscous fluid with asymmetric scatterers
E. Walker, A. Neogi, A. Bozhko +4
Two common concepts of nonreciprocity in sound propagation are based on nonlinear effects [1, 2] and on local circulation of fluid [3, 4]. They originate from two known methods of…
