A Proof that Multiple Waves Propagate in Ensemble-Averaged Particulate Materials
Artur Lewis Gower, Ian David Abrahams, William J. Parnell
Effective medium theory aims to describe a complex inhomogeneous material in terms of a few important macroscopic parameters. To characterise wave propagation through an inhomogene…

Multiple Waves Propagate in Random Particulate Materials
Artur Lewis Gower, William J. Parnell, Ian David Abrahams
For over 70 years it has been assumed that scalar wave propagation in (ensemble-averaged) random particulate materials can be characterised by a single effective wavenumber. Here,…
