Elastic and acoustic wave band structure

TL;DR: In this paper, a radial multi-layered elastic metamaterial (EM) shaft with rotational symmetry was proposed to reduce the total structural weight by 34% and showed that the proposed shaft can still yield broadband gaps at low-frequencies.

TL;DR: In this paper, a periodic truss beam is designed by connecting an array of identical elements in parallel to gain excellent Bragg band gaps, after which locally resonant (LR) oscillators are attached to the truss.

TL;DR: In this article, the scattering of plane elastic waves by multiple periodic arrays of interface strip-like cracks is investigated, and the boundary value problem is solved using the boundary integral equation method.

TL;DR: In this paper, the dispersion relations and the band gap properties of 2D phononic crystals with periodically arranged nanoholes or nanofibers are studied and the scattering matrix of a single scatterer is derived from a set of nontraditional boundary conditions based on the surface elasticity theory.

TL;DR: In this article, a simple model for spin diffusion or conduction in the "impurity band" is presented, which involves transport in a lattice which is in some sense random, and in them diffusion is expected to take place via quantum jumps between localized sites.

TL;DR: A new mechanism for strong Anderson localization of photons in carefully prepared disordered dielectric superlattices with an everywhere real positive dielectrics constant is described.

TL;DR: In this article, a review of the progress made in the last several years in understanding the properties of disordered electronic systems is presented, focusing on the metal-to-insulator transition and problems associated with the insulator.
