One-Dimensional Wave Dispersion in Layered Media
Abstract. Homogenisation theory reveals that long one-dimensional waves propagating in a medium with spatially periodic wave speed can behave like dispersive waves in an appropriately homogenised medium. However the precise time and length scales over which this dispersive behaviour is a good approximation are not clear. This paper describes what happens in a specific case when the sound speed ...
متن کاملTwo-Dimensional Wave Propagation in Layered Periodic Media
We study two-dimensional wave propagation in materials whose properties vary periodically in one direction only. High order homogenization is carried out to derive a dispersive effective medium approximation. One-dimensional materials with constant impedance exhibit no effective dispersion. We show that a new kind of effective dispersion may arise in two dimensions, even in materials with const...
متن کاملRecursive Dispersion Relations in One-Dimensional Periodic Elastic Media
A frequency bandgap is a range of wave frequencies that are prohibited from passing through a medium. The dispersion relation, which links the frequency to the wave number, enables us to illustrate the bandgaps. In [E. H. Lee, “A survey of variational methods for elastic wave propagation analysis in composites with periodic structures,” in Dynamics of Composite Materials, E. H. Lee, ed., ASME, ...
متن کاملDispersion Estimates for One-dimensional Discrete Schrödinger and Wave Equations
We derive dispersion estimates for solutions of the one-dimensional discrete perturbed Schrödinger and wave equations. In particular, we improve upon previous works and weaken the conditions on the potentials. To this end we also provide new results concerning scattering for one-dimensional discrete perturbed Schrödinger operators which are of independent interest. Most notably we show that the...
متن کاملWave Propagation in Randomly Layered Media
An acoustical pulse propagating in a randomly layered slab and scattered by the random inhomogeneities generates a reeected signal and a transmitted pulse followed by its coda. In the regime of separation of scales (correlation length of the random inhomogeneities much smaller than typical wavelengths contained in the pulse much smaller than the large scale of the medium comparable to the size ...
