We analyze the problem of a heterogeneous formulation of the equation of motion and
propose a new 3D fourth-order staggered-grid finite-difference (FD) scheme for modeling …

Modelling large-scale wave fields and their interaction with coastal and offshore structures
has become much more feasible over the last two decades with increases in computer …

This book focuses on basic and advanced concepts of wave propagation in diverse material
systems and structures. Topics are organized in increasing order of complexity for better …

A novel, hierarchical Haar wavelet basis is introduced and used to discretise the angular
dimension of the Boltzmann transport equation. This is used in conjunction with a finite …

In this paper, a novel wavelet based spectral finite element is developed for studying elastic
wave propagation in 1-D connected waveguides. First the partial differential wave equation …

The multiresolution capability provided by the family of Daubechies wavelets is exploited to
develop a new computational approach, termed as multiresolution finite wavelet domain …

Modeling long-range propagation of electromagnetic waves is necessary to study the
performance of systems, for applications such as radar or navigation. Such models generally …

A split-step wavelet method for simulating the long-range wave propagation is introduced. It
is based on the fast wavelet transform. Compared to the split-step Fourier method, this …

The nonlinear interaction of a dual-frequency Lamb wave with a breathing edge-crack leads
to the generation of frequency sidebands in the response spectrum; a phenomenon referred …

The crustally guided shear wave, Lg, is typically the most prominent phase of a nuclear
explosion at regional distance. This Lg phase is analyzed often to discriminate a nuclear …
