Elastic and acoustic wave band structure

TL;DR: In this paper, the authors introduced the concept of semi-infinite phononic crystal (PC) on account of the infinite periodicity in x-y plane and finiteness in z-direction.

TL;DR: This study presents a novel phononic crystal design with a silicon rubber connecting plate, achieving an ultrawide band gap (122.47-4360.2 Hz) with a lattice constant of 8.5 mm, and identifies key geometric parameters influencing the band gap.

TL;DR: In this paper , the authors investigated the attenuation effect of the pile barrier in blocking seismic surface waves by using theoretical and numerical methods, and derived the dispersion characteristics of pile barriers embedded in soil from the perspective of periodicity theory.

TL;DR: In this article, a new zigzag lattice phononic crystal with holes was designed and a nondominated sorting genetic algorithm-II (NSGA-II) was used for the optimization.

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.
