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…
Static elastic cloaking, low frequency elastic wave transparency and neutral inclusions
Andrew N. Norris, William J. Parnell
New connections between static elastic cloaking, low frequency elastic wave scattering and neutral inclusions are established in the context of two dimensional elasticity. A cylind…
Experimental Realization of Acoustic Bianisotropic Gratings
Steven R. Craig, Xiaoshi Su, Andrew N. Norris +1
Acoustic bianisotropic materials couple pressure and local particle velocity fields to simultaneously excite monopole and dipole scattering, which results in asymmetric wave transm…
Non-symmetric flexural wave scattering and one-way extreme absorption
Andrew N. Norris, Pawel Packo
The possibility of asymmetric absorption and reflection for flexural waves is demonstrated though analytical and numerical examples. We focus on the 1D case of flexural motion of a…
