On the existence of surface waves in an elastic half-space with impedance boundary conditions
(ELSEVIER SCIENCE BV, 2012)
In this work, the problem of surface waves in an isotropic elastic half-space with impedance boundary conditions is investigated. It is assumed that the boundary is free of normal traction and the shear traction varies ...
On the Green's function for the Helmholtz operator in an impedance circular cylindrical waveguide
(ELSEVIER, 2010)
This paper addresses the problem of finding a series representation for the Green's function of the Helmholtz operator in an infinite circular cylindrical waveguide with impedance boundary condition. Resorting to the Fourier ...
THEORETICAL ASPECTS AND NUMERICAL COMPUTATION OF THE TIME-HARMONIC GREEN'S FUNCTION FOR AN ISOTROPIC ELASTIC HALF-PLANE WITH AN IMPEDANCE BOUNDARY CONDITION
(EDP SCIENCES S A, 2010)
This work presents an effective and accurate method for determining, from a theoretical and computational point of view, the time-harmonic Green's function of an isotropic elastic half-plane where an impedance boundary ...
Comparative study of models of impedance boundary conditions in acoustic problems

The Helmholtz equation in a locally perturbed half-plane with passive boundary
(OXFORD UNIV PRESS, 2006)
In this article, we study the existence and uniqueness of outgoing solutions for the Helmholtz equation in locally perturbed half-planes with passive boundary. We establish an explicit outgoing radiation condition which ...
Homogenization Techniques for Improving the Calculations of Scattering by 1-D Fast Oscillating Periodic Surfaces
(2019)
This paper deals with the efficient computation of scattering problems by fast oscillating periodic surfaces using two-scale expansion homogenization techniques. The proposed method splits the field between an effective ...
