    We consider the discretization of electromagnetic wave propagation problems by a discontinuous Galerkin method based on Trefftz polynomials. This method fits into an abstract framework for space-time discontinuous Galerkin methods for which we can prove consistency, stability, and energy dissipation without the need to completely specify the approximation spaces in detail. cal physics: wave propagation and kinetic theory of gases. Various mathematical and computational problems for equations from these areas are treated. The first part is devoted to high order finite difference methods for the Helmholtz equa-tion and the wave equation. Compact schemes with high order accuracy are obtained.

e.g., [1]). Unfortunately, the majority of these numerical methods produce. This series of books deals with the mathematical modeling and computational simulation of complex wave propagation phenomena in science and engineering.

This first volume of the series introduces the basic mathematical and physical fundamentals, and it is mainly intended as a reference guide and a general survey for scientists and engineers.

Introducing computational wave propagation methods developed over 40 years of research, this comprehensive book offers a computational approach to NDE of isotropic, anisotropic, and functionally graded materials.

It discusses recent methods to enable enhanced computational efficiency for anisotropic materials. This book builds on the introduction of spectral analysis as a means of investigating wave propagation and transient oscillations in structures. Finite element methods are now integrated into the spectral analyses to gain further insights into the high-frequency problems.

This book begins with the simulation of nonlinear. An effective parameters retrieval method based on the wave propagation simulation is proposed and compared with the standard S-parameter procedure.

The method is free from possible mistakes originated by the multiple branching of solutions in the S-parameter procedure and shows high accuracy.

The limitations of the new method are discussed. () A ray-based IPDG method for high-frequency time-domain acoustic wave propagation in inhomogeneous media. Journal of Computational Physics() A conservative local multiscale model reduction technique for Stokes flows in heterogeneous perforated domains.

In addition, various multiscale methods, for simulating wave propagation are presented in the literature. For instance, multiscale finite element methods (MsFEM) [21], [22] and the heterogeneous multiscale methods (HMM) [1], [2], [3] are proposed to discretize the wave.

The CST results for the group velocity and wave propagation response to tone burst excitation show significant deviation from the FSDT results for out-of-plane A 0 flexural mode even at relatively low frequencies. The orthotropy ratio and lamination arrangements in a composite shell panel have significant effect on the group velocity as well as.

Two other recently developed methods (not discussed in this volume) for wave propagation in laterally heterogeneous media are the wave scattering method of Aki and Larner (; Larner, ) and the perturbation method of Claerbout (a, b, ), Claerbout and Johnson (), and Landers ().

Book Description Introducing computational wave propagation methods developed over 40 years of research, this comprehensive book offers a computational approach to NDE of isotropic, anisotropic, and functionally graded materials.

It discusses recent methods to enable enhanced computational efficiency for anisotropic materials. The pitch-catch guided-wave propagation method for damage detection is also known as acousto-ultrasonics because, as indicated in Ref.

[12], the method combines an excitation similar to that used in ultrasonics with an analysis of the detected signal similar to that used in acoustic emission monitoring Pulse-Echo Guided-Wave Propagation SHM.

Explicit formulas and efficient computational algorithms for the calculation of the effective properties of the composites are presented and analyzed. The method of the effective medium and the method of the effective field are developed for the calculation of the phase velocities and attenuation of the mean (coherent) wave fields propagating.

Computational methods for wave propagation are essential in many fields of application, such as acoustics, structural dynamics, geophysics, electromagnetics and fluid-structure interaction. In recent years there has been an increased interest in advanced computational methods for.

Wave propagation methods become popular techniques in the evaluation of stiffness of geomaterials and process monitoring both in the laboratory and in the field (Richart et al.Matthews et al.Santamarina et al.LoPresti et al.

).Table 1 summarizes the existing wave propagation methods used by the geoengineering community in the U.S.Earthquakes, a plucked string, ocean waves crashing on the beach, the sound waves that allow us to recognize known voices.

Waves are everywhere, and the propagation and classical properties of these apparently disparate phenomena can be described by the same mathematical methods: variational calculus, characteristics theory, and caustics.
