Phononic crystals are composite materials made of periodic distributions of inclusions
embedded in a matrix. Due to their periodic structure, these materials may exhibit under …

Phononic crystals (PnCs) are novel synthetic periodic materials for controlling and
manipulating the propagation of elastic (or acoustic) waves. The periodic nature of PnCs …

Various effects of elastic and piezoelectric nonlinearity on the propagation of surface
acoustic waves are discussed and methods for their theoretical analysis are described …

Cottam and Tilley provide an introduction to the properties of wave-like excitations
associated with surfaces and interfaces. The emphasis is on acoustic, optic and magnetic …

Acoustic waves localized at the surface of two-dimensional (2D) periodic elastic structures,
or 2D phononic crystals, are studied theoretically by taking account of the elastic anisotropy …

As supervised learning has been successfully applied in mechanics, reinforcement learning
is being attempted to be used to solve mechanical problems more intelligently. In this study …

We present a review, through selected illustrative examples, of the physics of classical
vibrational modes in phononic lattices, which elaborates on the theory, the formalism, the …

We present the results of picosecond ultrasonic studies of localized acoustic-phonon surface
modes in Al/Ag superlattices. By making measurements on a series of superlattices with …

The propagation of longitudinal and transverse elastic waves oblique or perpendicular to the
laminations of infinite periodically layered fourfold system is studied. Comprehensive study …

It is unanimously accepted that the quantum and the classical descriptions of the physical
reality are very different, although any quantum process is" mysteriously" transformed …
