Viscoelastic Rayleigh waves [PDF]
Quarterly of Applied Mathematics, 1977 A general analysis is given of the propagation of surface waves over a half-space of homogeneous isotropic linearly-viscoelastic material. Particular emphasis is placed on the properties of the particle paths. The detailed examination of particular models shows that (in contrast with elastic materials) (i) more than one surface wave may be possible ...

Disturbances of surface wave field due to wave scattering at shallow cavities
Yantu gongcheng xuebao, 2018 In homogenous half spaces, the wave fields at shallow depth are dominated by Rayleigh waves activated by the surface sources. When the forward Rayleigh waves encounter a shallow cavity, the displacement shapes and the particle orbit are changed. Rayleigh

Efficiency of Higher Order Finite Elements for the Analysis of Seismic Wave Propagation [PDF]
, 2000 The analysis of wave propagation problems in linear damped media must take into account both propagation features and attenuation process. To perform accurate numerical investigations by the finite differences or finite element method, one must consider ...

Resonance Expansions and Rayleigh Waves [PDF]
Mathematical Research Letters, 2001 The author studies expansions of solutions of the wave equation in a compact set with initial data supported in the same set. He considers the general framework of the ``black box scattering'' introduced by Sjöstrand and Zworski. In particular, this includes the classical case of scattering by obstacle with Dirichlet or Neumann boundary conditions and ...

“Forbidden” planes for Rayleigh waves [PDF]
Quarterly of Applied Mathematics, 2002 Summary: We discuss the existence of ``forbidden'' planes, on which Rayleigh waves cannot propagate. A mathematical model for anisotropic materials possessing ``forbidden'' planes is constructed, and an example of transversely isotropic material having ``forbidden'' planes is presented.

Imaging of Biphoton States: Fundamentals and Applications
Advanced Functional Materials, EarlyView.Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Advanced Functional Materials, EarlyView.Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
