TL;DR: In this article, a large-scale Rb0.3MoO3 crystal was synthesized using the molten salt electrolysis method and the lattice constants were evaluated from X-ray diffraction (XRD) patterns and rocking curves.

TL;DR: In this paper, the authors studied the formation and properties of acoustic surface-guided modes at the interface of two phononic crystals (PCs) and demonstrated that in the shared region of the frequency gaps, the SGMs can exist at the interfaces as a result of total reflections from both PCs, which causes the formation of nodal planes by the interference of the forward and backward propagation waves.

TL;DR: In this paper, the authors describe the fabrication of an annular anisotropic metamaterial with an azimuthal effective density approaching zero and demonstrate its robust omnidirectional radiation performance.

TL;DR: In this paper, the authors extended the Rayleigh identity based on a multipole expansion theory to analyze the mechanical properties of a new type of electrorheological (ER) system that consists of a doubly coated particle in silicone oil.

TL;DR: In this article, the omnidirectional effective acoustic parameters for the metafluid consisting of isotropic fluid cylinders embedded in an anisotropic fluid background were derived within a unified theoretical framework, and a simple expression for the effective mass density parallel to the cylinders was derived.
