The modern scope of boundary element methods (BEM) for acoustics is reviewed in this
paper. Over the last decades the BEM has gained popularity despite suffering from …

We present an efficient matrix-free geometric multigrid method for the elastic Helmholtz
equation, and a suitable discretization. Many discretization methods had been considered in …

In this paper, a fast multipole method (FMM) is proposed to compute long-range interactions
of wave sources embedded in 3-dimensional (3-D) layered media. The layered media …

In this paper, we first derive the multipole expansion (ME) and local expansion (LE) for far
fields from wave sources in two-dimensional (2-D) layered media as well as the multipole-to …

In this paper, a fast multipole method (FMM) is proposed for 3-D Laplace equations in
layered media. The potential due to charges embedded in layered media is decomposed …

We present a novel block-preconditioner for the elastic Helmholtz equation, based on a
reduction to acoustic Helmholtz equations. Both versions of the Helmholtz equations are …

A novel method is presented to accurately determine the operational range of an on-body,
passive ultrahigh-frequency (UHF) radio frequency identification (RFID) system operating in …

We propose an accurate algorithm for a novel sum-of-exponentials (SOE) approximation of
kernel functions, and develop a fast algorithm for convolution quadrature based on the SOE …

In this paper, we propose a fast multipole method (FMM) for 3-D linearized Poisson–
Boltzmann (PB) equation in layered electrolyte-dielectric media. We will extend our previous …

Purpose This meshless collocation method is applicable not only to the Helmholtz equation
with Dirichlet boundary condition but also mixed boundary conditions. It can calculate not …
