Elastic wave propagation along waveguides in three-dimensional phononic crystals

We investigate theoretically using the finite difference time domain method acoustic wave propagation along waveguides in three-dimensional phononic crystals constituted of lead spherical inclusions on a face-centered cubic lattice embedded in an epoxy matrix. The transmission spectra of the perfect phononic crystal for transverse and longitudinal acoustic waves are shown to depend strongly on ...

Seismic Wave-Field Propagation Modelling using the Euler Method

Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy. It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. Moreover, the main drawbacks of the finite difference method are the low level of accuracy and the numerical dispersion for l...

Analytical D’Alembert Series Solution for Multi-Layered One-Dimensional Elastic Wave Propagation with the Use of General Dirichlet Series

A general initial-boundary value problem of one-dimensional transient wave propagation in a multi-layered elastic medium due to arbitrary boundary or interface excitations (either prescribed tractions or displacements) is considered. Laplace transformation technique is utilised and the Laplace transform inversion is facilitated via an unconventional method, where the expansion of complex-valued...

Elastic Wave Propagation along Layers in Two- Dimensional Models

594 BULLETIN OF THE SEISMOLOGICAL SOCIETY OF AMERICA It was shown by Oliver, Press, and Ewing (1954) that propagation in twodimensional models is representative of that along the plane of propagation in three-dimensionM eases when the longitudinal plate velocity in the two-dimensional medium is replaced by the corresponding wave velocity in the three-dimensional ease. The observed amplitude dis...

SiD2 using three-dimensional wave packet propagation

Dissociations after the à B1→ B̃ A1 photoexcitation of SiH2, SiHD, and SiD2 were studied to investigate excited-state dynamics and effects of the initial vibrational state. The cross section for the photodissociation relative to SiH2 B̃ →Si D +H2 and the rovibrational population of the H2 fragment were computed using the wave packet propagation technique based on the three-dimensional potential e...
