A Numerical Model of an Acoustic Metamaterial Using the Boundary Element Method Including Viscous and Thermal Losses

Cutanda-Henriquez, V.; Andersen, Peter Risby; Jensen, J. Sondergaard; Juhl, P. Moller; Sánchez-Dehesa Moreno-Cid, José (World Scientific, 2017)

[EN] In recent years, boundary element method (BEM) and finite element method (FEM) implementations of acoustics in fluids with viscous and thermal losses have been developed. They are based on the linearized Navier¿Stokes ...
Numerical modeling of double-negative acoustic metamaterials: Should losses be included?

Cutanda Henriquez, Vicente; Andersen, Peter Risby; Sánchez-Dehesa Moreno-Cid, José (Universidade do Porto, 2016-06-15)

[EN] Viscous and thermal losses of acoustic waves are usually neglected or accounted for as boundary impedance. It is known, however, that acoustic losses become relevant in devices with some dimension in the millimeter ...
