Frequency sweeps in structural dynamics, acoustics, and vibro‐acoustics require evaluating
frequency response functions for a large number of frequencies. The brute force approach …

Many of the current issues and methodologies related to finite element methods for time-
harmonic acoustics are reviewed. The effective treatment of unbounded domains is a major …

This paper addresses the first step of the derivation of well-conditioned integral formulations
for the iterative solution of exterior acoustic boundary-value problems. These new …

We introduce a coupled finite and boundary element formulation for acoustic scattering
analysis over thin‐shell structures. A triangular Loop subdivision surface discretisation is …

A new artificial boundary condition for two-dimensional acoustic scattering problems is
constructed in this paper. It is designed from the principal symbol of the Dirichlet-to …

An optimized version of the so‐called mapped wave envelope elements, also known as
Astley–Leis elements, is introduced. These elements extend to infinity in one dimension and …

We study the application of a B-splines Finite Element Method (FEM) to time-harmonic
scattering acoustic problems. The infinite space is truncated by a fictitious boundary and …

Using Brillouin light scattering measurements, we have studied the properties of the spin
waves in various arrays of Permalloy wires showing widths of 0.5, 1, and 1.5 μm. When the …

We report on a generalization of the Bayliss–Gunzburger–Turkel non‐reflecting boundary
conditions to arbitrarily shaped convex artificial boundaries. For elongated scatterers such …

Frequency sweep problems arise in many structural dynamic, acoustic, and structural
acoustic applications. In each case, they incur the evaluation of a frequency response …
