Principles and properties of phononic crystal waveguides

APL Materials, 2021
Strongly confined waveguiding is one of the main applications of phononic crystals that can be achieved at any frequency and scale. Phononic crystal waveguides replace the cladding of classical homogeneous waveguides by a crystal possessing a complete ...

Band Profile and Surface Acoustic Wave Attenuation Analysis of Polygonal Cavity-type Piezoelectric Phononic Crystals

Physics and Astronomy Reports, 2023
In this study, we examined the dispersion profiles and surface acoustic wave attenuation properties of polygonal cavity-type phononic crystals in relation to changes in the number of vertices. Both band analysis and transmission spectrum calculations are

Band gap engineering in simultaneous phononic and photonic crystal slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail

Towards tunable graphene phononic crystals [PDF]

, 2023
Phononic crystals (PnCs) are artificially patterned media exhibiting bands of allowed and forbidden zones for phonons. Many emerging applications of PnCs from solid-state simulators to quantum memories could benefit from the on-demand tunability of the ...

Tacticity in chiral phononic crystals. [PDF]

Nat Commun, 2019
AbstractThe study of vibrational properties in engineered periodic structures relies on the early intuitions of Haüy and Boscovich, who regarded crystals as ensembles of periodically arranged point masses interacting via attractive and repulsive forces.

Phonon manipulation with phononic crystals [PDF]

, 2012
In this work, we demonstrated engineered modification of propagation of thermal phonons, i.e. at THz frequencies, using phononic crystals. This work combined theoretical work at Sandia National Laboratories, the University of New Mexico, the University of Colorado Boulder, and Carnegie Mellon University; the MESA fabrication facilities at Sandia; and ...

Optimization of spider web-inspired phononic crystals to achieve tailored dispersion for diverse objectives

Materials & Design, 2021
Spider orb webs are versatile multifunctional structures with optimized mechanical properties for prey capture, but also for transmitting vibrations. The versatility of such a system mainly derives from its variable geometry, which can be effectively ...

Simultaneous Existence of Phononic and Photonic Band Gaps in Phoxonic Crystal Slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell ...
