Waves over a periodic progressive modulation: A python tutorial
Hussein Nassar, Andrew N. Norris, Guoliang Huang
This chapter presents a selection of theoretical and numerical tools suitable for the study of wave propagation in time-dependent media. The focus is on one-dimensional spring-mass…
Constant intensity acoustic propagation in the presence of non-uniform properties and impedance discontinuities: Hermitian and non-Hermitian solutions
Andrew N. Norris
Propagation of sound through a non-uniform medium without scattering is possible, in principle, if the density and acoustic compressibility assume complex values, requiring passive…
Unilateral and nonreciprocal transmission through bilinear spring systems
Zhaocheng Lu, Andrew N. Norris
Longitudinal wave propagation is considered in a pair of waveguides connected by bilinear spring systems. The nature of the nonlinearity causes the compressive and tensile force-di…
Metaclusters for the Full Control of Mechanical Waves
Pawel Packo, Andrew Norris, Dani Torrent
We present a new method for the control of waves based on inverse multiple scattering theory. Conceived as a generalization of the concept of metagrating, we call metaclusters to a…
E2 distribution and statistical regularity in polygonal planar tessellations
Ran Li, Consuelo Ibar, Zhenru Zhou +4
From solar supergranulation to salt flat in Bolivia, from veins on leaves to cells on Drosophila wing discs, polygon-based networks exhibit great complexities, yet similarities per…
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…
