Maximizing the electromomentum coupling in piezoelectric laminates
Majd Kosta, Alan Muhafra, René Pernas Salomón +2
Asymmetric piezoelectric composites exhibit coupling between their macroscopic linear momentum and electric field, a coupling that does not appear at the microscopic scale. This el…
Fundamental principles for generalized Willis metamaterials
René Pernas-Salomón, Gal Shmuel
Metamaterials whose momentum is constitutively coupled with their strain show promise in wave manipulation for engineering purposes and are called Willis materials. They were disco…
Oscillating vector solitary waves in soft laminates
Ron Ziv, Gal Shmuel
Vector solitary waves are nonlinear waves of coupled polarizations that propagate with constant velocity and shape. In mechanics, they hold the potential to control locomotion, mit…
Linking scalar elastodynamics and non-Hermitian quantum mechanics
Gal Shmuel, Nimrod Moiseyev
Recent years have seen a fascinating pollination of ideas from quantum theories to elastodynamics---a theory that phenomenologically describes the time-dependent macroscopic respon…
Anomalous energy transport in laminates with exceptional points
Ben Lustig, Guy Elbaz, Alan Muhafra +1
Recent interest in metamaterials has led to a renewed study of wave mechanics in different branches of physics. Elastodynamics involves a special intricacy, owing to a coupling bet…
Symmetry Breaking Creates Electro-Momentum Coupling in Piezoelectric Metamaterials
René Pernas-Salomón, Gal Shmuel
Metamaterials posses microstructure designed to acquire properties not found in nature. An epitome in acoustics and solid mechanics is Willis coupling, which refers to the particle…
