From solar supergranulation to salt flats in Bolivia, from veins on leaves to cells on Drosophila wing disks, polygon-based networks exhibit great complexities, yet similarities and consistent patterns emerge. Based on analysis of 99 polygonal tessel

A metamaterial of particular interest for underwater applications is the three-dimensional (3D) anisotropic pentamode (PM), i.e., a structure designed to support a single longitudinal wave with a sound speed that depends on the propagation direction.

A passive method of realizing nonreciprocal wave propagation in a two-dimensional (2D) lattice is proposed, using bilinear springs combined with the necessary spatial asymmetry to provide a stable and strong departure from reciprocity. The bilinear p

The law of reciprocity in acoustics and elastodynamics codifies a relation of symmetry between action and reaction in fluids and solids. In its simplest form, it states that the frequency-response functions between any two material points remain the

2021 Fifteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).
Acoustic and elastic metamaterials with space- and time-dependent material properties have received great attention recently as a means to realize systems that are not linear-time-invariant, usually with the goal to induce nonreciprocal wave propagat

Significant research over the last decade has focused on elastostatic metamaterials and particularly elastostatic cloaking. A related concept is the "neutral inclusion" (NI): a coated region, where the coating is designed such that fields in the exte
