title = "Effective impedance models for rough surfaces in time-domain propagation methods",
abstract = "Ground surface roughness exhibits complex geometry and may be not accurately known. Using an effective impedance model in numerical methods for sound propagation could avoid meshing the small irregularities and then reduce computation time. The effective impedance model proposed by Attenborough et al. considers surface roughness as small scatterers with a constant geometry regularly or randomly spaced on the propagation path. This effective impedance model is transposed in time-domain and tested in two propagation codes (FDTD and Transmission Line Matrix). First results of computations are exposed.",
