TLDR
In this article, the authors apply the material developed in the Volume One to various boundary value problems (reflection and refraction at plane surfaces, composite media, waveguides and resonators).Abstract:
This work, part of a two-volume set, applies the material developed in the Volume One to various boundary value problems (reflection and refraction at plane surfaces, composite media, waveguides and resonators). The text also covers topics such as perturbation and variational methods.read more

Elastic properties of Ti,Al,Si N nanocomposite films
TL;DR: In this article, the Young's modulus was evaluated by both depth-sensing indentation and surface acoustic wave (SAW) techniques, and the results revealed systematically higher values than those obtained by SAW.
Journal ArticleDOI
Real ray tracing in anisotropic viscoelastic media
TL;DR: In this article, the authors derived ray tracing equations applicable to smoothly inhomogeneous anisotropic viscoelastic media, in contrast to previous ray-theoretical approaches, which deal with complex rays.

Wide-band acoustically coupled thin-film BAW filter
Johanna Meltaus,Tuomas Pensala +1 more
TL;DR: In this paper, the authors proposed a bulk acoustic wave (BAW) filter based on laterally acoustically coupled resonators on piezoelectric thin films, which can utilize two distinct acoustic plate wave modes of different nature, for example the thickness extensional (longitudinal) TE1 and the second harmonic thickness shear (TS2) mode to form a bandpass response.
Journal ArticleDOI
Theory of surface vibrations in epitaxial thin films
TL;DR: Detailed slab calculations for Na/Cu(001) confirm this model and indicate that the observed flat phonon dispersion curves are related to the strength of the interface interaction and bcc structure of the epitaxially grown Na thin films.
Journal ArticleDOI
The reflection phenomena of quasi-vertical transverse waves in piezoelectric medium under initial stresses
TL;DR: In this paper, the propagation of plane vertical transverse waves at an interface of a semi-infinite piezoelectric elastic medium under the influence of the initial stresses is discussed.

Physical properties of crystals
TL;DR: In this paper, the physical properties of crystals systematically in tensor notation are presented, presenting tensor properties in terms of their common mathematical basis and the thermodynamic relations between them.

Field theory of guided waves
TL;DR: In this paper, the authors present a model for waveguide decomposition in terms of waveguide discontinuities and waveguides and cavities, and apply it to artificial dielectrics.
