Metamaterials enable the realization of unique material properties such as coupling between strain and momentum in a fluid—known as Willis coupling. Here, Muhlesteinet al. use homogenization theory to better understand Willis coupling in acoustic m

The nonlinear evolution of high-amplitude broadband noise is important to the psychoacoustic perception, usually annoyance, of high-speed jet noise. One method to characterize the nonlinear evolution of such noise is to consider a characteristic nonl

A class of metamaterials that exhibit mass-momentum coupling are known as Willis materials. The mass-momentum coupling arises from hidden degrees of freedom that are asymmetrical with respect to the overall material. Resonant Willis metamaterials inc

The impacts of characteristic weather events and seasonal patterns on infrasound propagation in the Arctic region are simulated numerically. The methodology utilizes wide-angle parabolic equation methods for a windy atmosphere with inputs provided by

Acoustic metameterials are an increasingly popular approach to control both linear and nonlinear sound propagation. In this approach, heterogeneous structures are engineered to behave as predetermined continuous media. A key requirement for a system

Efforts to reduce the full second-order nonlinear equations of motion down to a single nonlinear wave equation are frustrated by the presence of the Lagrangian density, a combination of terms that involve both the particle velocity and the acoustic p

The framework of the numerical scheme presented in this talk is that of the finite-difference time-domain (FDTD) method published by Sparrow and Raspet [J. Acoust. Soc. Am. 90, 1991]. The method is fourth-order in space and second-order in time when

Wide-angle parabolic equations (WAPEs) play an important role in physics. They are derived by an expansion of a square-root pseudo-differential operator in one-way wave equations, and then solved by finite-difference techniques. In the present paper,
