Abstract Experiments on ultrasound propagation through a gel doped with resonant encapsulated microbubbles provided evidence for a discontinuous transition between wave propagation regimes at a critical excitation frequency. Such behavior is unlike t

Anderson localization is a disorder-driven phenomenon typically considered in the context of low-temperature condensed-matter systems. However, the phenomenon can also be relevant to soft matter and here the authors experimentally demonstrate it is p

Here, authors report on acoustic cavities in 2D materials operating in the 50–600 GHz range and show that quality factors approach the limit set by lattice anharmonicity. Functionality expanded by heterogeneities (steps and interfaces) is demonstra

Abstract Free standing, atomically thin transition metal dichalcogenides are a new class of ultralightweight nanoelectromechanical systems with potentially game-changing electro- and opto-mechanical properties, however, the energy dissipation pathway

This article describes the development and testing of a passive sonar, multitarget tracker, and adaptive behavior that enable an autonomous underwater vehicle (AUV) to detect and actively track nearby surface vessels. A planar hull-mounted hydrophone

The Orbiting Dubins Traveling Salesman Problem (ODTSP) is to plan a minimum-time tour for a Dubins vehicle model to inspect a set of targets in the plane by orbiting each target along a circular arc. This problem arises in underwater minehunting, whe

In this paper, we describe an unmanned underwater vehicle (UUV) behavior designed to track nearby vessels using bearing-only measurements obtained from a rigidly mounted planar hydrophone array—one that was originally designed for active sonar use

The ability to generate transversely propagating elastic waves on free-standing semiconductor films in the 10+ GHz frequency range is a critical element in the effort to achieve phonon-based coupling to on-chip electronic devices. The results of this

A material's acoustic properties depend critically upon porosity. Doping a soft material with gas-filled microballoons permits a controlled variation of the porosity through a scalable fabrication process while generating well-tailored spherical cavi
