Elastic and acoustic wave band structure

TL;DR: In this paper, the authors studied one-dimensional phononic structures for selective acoustic filtering and observed that the phononic band gaps split in two and three transmission valleys for the three-material and four-material based phononic structure, respectively.

TL;DR: In this article, the acoustic properties of a hybrid composite that exhibits both photonic and phononic behavior are investigated numerically with finite-element and finite-difference time-domain simulations.

TL;DR: In this paper, the wave dispersion properties of multi-story reinforced concrete frame building structures were investigated using the infinite periodic model and the State-Space-Transfer-Matrix-Method (SSTMM).

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.
