We introduce an optimal bounded Perfectly Matched Layer (PML) technique by choosing a particular absorbing function with unbounded integral. With this choice, spurious reflections are avoided, even… (More)

This paper deals with the approximation of the vibration modes of a plate modelled by the Reissner-Mindlin equations. It is well known that, in order to avoid locking, some kind of reduced… (More)

The main goal of this work is to give a review of the Perfectly Matched Layer (PML) technique for time-harmonic problems. Precisely, we focus our attention on problems stated in unbounded domains,… (More)

The aim of this paper is to introduce an “exact” bounded perfectly matched layer (PML) for the scalar Helmholtz equation. This PML is based on using a non integrable absorbing function. “Exactness”… (More)

We present an optimal bounded Perfectly Matched Layer (PML) by choosing a particular absorbing function with unbounded integral. With this choice, any spurious reflection is avoided even when the… (More)

Abstract. A modal synthesis method to solve the elastoacoustic vibration problem is analyzed. A two-dimensional coupled fluid-solid system is considered; the solid is described by displacement… (More)

We consider the following Helmholtz problem which models the propagation of a wave of frequency ω > 0 and velocity of propagation c > 0 in an unbounded homogeneous medium: ∆u + k2u = 0 in ΩE,… (More)
