Propagation of scalar waves in dense disordered media exhibiting short- and long-range correlations

Autor: Adrien Rohfritsch, Jean-Marc Conoir, Tony Valier-Brasier, Romain Pierrat, Régis Marchiano

Publikováno v: Physical Review E. 104

Correlated disorder is at the heart of numerous challenging problematics in physics. In this work we focus on the propagation of acoustic coherent waves in two-dimensional dense disordered media exhibiting long- and short-range structural correlation

Impact of particle size and multiple scattering on the propagation of waves in stealthy-hyperuniform media

Autor: Tony Valier-Brasier, Jean-Marc Conoir, Régis Marchiano, Adrien Rohfritsch

Publikováno v: Physical Review E
Physical Review E, American Physical Society (APS), 2020, ⟨10.1103/PhysRevE.102.053001⟩

International audience; Propagation of waves in materials that exhibit stealth-hyperuniform long range correlations is investigated. By using a modal decomposition of the field that takes multiple scattering into account at all orders, we study the i

Influence of the microstructure of two-dimensional random heterogeneous media on propagation of acoustic coherent waves

Autor: Jean-Marc Conoir, Adrien Rohfritsch, Régis Marchiano, Tony Valier-Brasier

Publikováno v: Physical review. E. 101(2-1)

Multiple scattering of waves arises in all fields of physics either in periodic or random media. For random media the organization of the microstructure (uniform or non-uniform statistical distribution of scatterers) has effects on the propagation of

Autor: Régis Marchiano, Jean-Marc Conoir, Adrien Rohfritsch, Tony Valier-Brasier

Publikováno v: Journal of the Acoustical Society of America
Journal of the Acoustical Society of America, Acoustical Society of America, 2019, 145 (6), pp.3320-3329. ⟨10.1121/1.5110310⟩

International audience; The purpose of this article is to present an innovative resolution method for investigating problems of sound scattering by infinite cylinders immersed in a fluid medium. The study is based on the analytical solution of multip
