This review article revisits and outlines the perfectly matched layer (PML) method and its
various formulations developed over the past 25 years for the numerical modeling and …

Precise and target-oriented control of acoustic/elastic wave bandgaps in phononic crystals
or acoustic metamaterials according to particular requirements is of both theoretical and …

In this paper, the manipulation of the guided elastic waves in periodically multilayered
elastic plates (PMEPs) by introducing interfacial delaminations is explored. A periodic array …

This paper presents an efficient semi-analytical hybrid approach for simulating the dynamic
interaction of perfectly bonded or damaged piezoelectric structures with a layered elastic …

A coupled thermo-mechanical simulation technique is proposed for reliability analyses of
electronic devices based on the spectral element time domain (SETD) method. The transient …

The band-gap frequencies of elastic metamaterials are ideally determined by a metamaterial
architecture; yet, in practical situations, are often dependent on the material damping in their …

Complex topography, the free-surface boundary condition, and anelastic properties of media
should be accounted for in the frame of onshore geophysical prospecting imaging, such as …

The mixed spectral-element method (MSEM) is applied to solve the waveguide problem with
the Bloch periodic boundary condition (BPBC). Based on the BPBC for the original …

Surface acoustic wave (SAW) devices are key components in 5G communication systems,
and the design of SAW filters with high frequency, high performance and high reliability is a …

In elastic wave inverse scattering problems, the material-property reconstruction, eg,
distributions of mass density, compressional wave speed, and shear wave speed from a …
