Non-reciprocal wave transmission in a bilinear spring-mass system
Zhaocheng Lu, Andrew N. Norris
Significant amplitude-independent and passive non-reciprocal wave motion can be achieved in a one dimensional (1D) discrete chain of masses and springs with bilinear elastic stiffn…

Acoustic scattering from a fluid cylinder with Willis constitutive properties
Michael B. Muhlestein, Benjamin M. Goldsberry, Andrew N. Norris +1
A material that exhibits Willis coupling has constitutive equations that couple the pressure-strain and momentum-velocity relationships. This coupling arises from subwavelength asy…
