Complex Spatiotemporal Modulations and Non-Hermitian Degeneracies in -Symmetric Phononic Materials
M. Moghaddaszadeh, M. A. Attarzadeh, A. Aref +1
Unraveling real eigenfrequencies in non-Hermitian -symmetric Hamiltonians has opened new avenues in quantum physics, photonics, and most recently, phononics. However,…
Frequency Selective Wave Beaming in Nonreciprocal Acoustic Phased Arrays
R. Adlakha, M. Moghaddaszadeh, M. A. Attarzadeh +2
Acoustic phased arrays are capable of steering and focusing a beam of sound via selective coordination of the spatial distribution of phase angles between multiple sound emitters.…
Metamodel Based Forward and Inverse Design for Passive Vibration Suppression
Amir Behjat, Manaswin Oddiraju, Mohammad Ali Attarzadeh +2
Aperiodic metamaterials represent a class of structural systems that are composed of different building blocks (cells), instead of a self-repeating chain of the same unit cells. Op…
Non-reciprocal Wave Phenomena in Energy Self-reliant Gyric Metamaterials
M. A. Attarzadeh, S. Maleki, J. L. Crassidis +1
This work presents a mechanism by which non-reciprocal wave transmission is achieved in a class of gyric metamaterial lattices with embedded rotating elements. A modulation of the…
Generalized Analysis of Elastic Wave Dispersion Asymmetries in Moving Periodic Media
M. A. Attarzadeh, M. Nouh
This work presents a generalized physical interpretation of unconventional dispersion asymmetries associated moving elastic solids. By shifting the notion from systems with time-va…
On the wave dispersion and non-reciprocal power flow in space-time traveling acoustic metamaterials
M. A. Attarzadeh, H. Al Ba'ba'a, M. Nouh
This note analytically investigates non-reciprocal wave dispersion in locally resonant acoustic metamaterials. Dispersion relations associated with space-time varying modulations o…
