This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

Acoustic metamaterials allow for creating selective pass-and stop-bands on the frequency
spectrum. We demonstrate the possibility of designing acoustic metamaterials as core-shell …

Wave invisibility in confined space has been proved practical significance in mechanical
engineering and military fields. In this work, a flexural wave cloak of a corner-domain target …

In this paper, we show how to efficiently achieve thermal cloaking from a computational
standpoint in several virtual scenarios by controlling a distribution of active heat sources. We …

We design sources for the two-dimensional Helmholtz equation that can cloak an object by
cancelling out the incident field in a region, without the sources completely surrounding the …

We consider the propagation of acoustic waves in a 2D waveguide unbounded in one
direction and containing a compact obstacle. The wavenumber is fixed so that only one …

Designing wideband thermal cloaks remains a challenge, especially at high frequencies.
We propose an optimization approach for the design of a thermal cloak for an arbitrary …

The diffusion of charged particles in a graph can be modeled using random walks on a
weighted graph. We give strategies to hide (or cloak) changes in a subgraph from the …

This chapter introduces the field of acoustic metamaterials in light of correspondences with
related phenomena in electromagnetics. The semantic frontier between phononic/photonic …

Heat is a by-product of any electronic circuit. It is unavoidable; however, an adequate
thermal management system can protect thermal sensitive components from catastrophic …
