Time domain scattering of acoustic plane waves by vertical faults
(1996)
Acoustic plane wave scattering at a vertical fault structure represents the simplest two-dimensional model of geophysical exploration that can be investigated by analytical techniques. The exact and complete solution, in ...
Convolution quadrature methods for time domain acoustic wave propagation in layered media and composite materials
(2019)
We present a novel computational scheme to solve time domain acoustic scattering
in two particular situations, using multistep and multistage Convolution Quadrature (CQ)
methods for a time domain discretization. First, we ...

(WALTER DE GRUYTER GMBH, 2022)
This is the preface of a special issue dedicated to the memory of Francisco Javier Sayas who passed away on April 2, 2019. The articles reflect Sayas' main research interests in the numerical analysis of partial differential ...
Perfectly matched layers.
(Marburg, S.Nolte, B.Springer, Berlin, Heidelberg, 2008)
This is a survey of some recent developments on the so called “Perfectly Matched Layer” (PML) method. We take as model the scattering problems in linear acoustics. First, the Cartesian PML equations are described in the ...
