Based on the perfectly matched layer (PML) technique, this paper develops a high-accuracy boundary integral equation (BIE) solver for acoustic scattering problems in locally defected layered media in…

### On the generalized Calderón formulas for closed- and open-surface elastic scattering problems

- MathematicsCSIAM Transactions on Applied Mathematics
- 2022

This work investigates weighted integral operators instead of the original integral operators which are resulted from dealing with edge singularities of potentials corresponding to the elastic scattering problems by open-surfaces, and proves that the Calderón formula is a compact perturbation of a bounded and invertible operator.

### Windowed Green Function Method for Layered-Media Scattering

- Computer ScienceSIAM J. Appl. Math.
- 2016

The WGF method, which is based on the use of smooth windowing functions and integral kernels that can be expressed directly in terms of the free-space Green function, does not require evaluation of expensive Sommerfeld integrals.

### Windowed Green function method for the Helmholtz equation in the presence of multiply layered media

- Computer ScienceProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2017

The proposed windowed Green function approach efficiently evaluates oscillatory integrals over unbounded domains, with high accuracy, without recourse to the highly expensive Sommerfeld integrals that have typically been used to account for the effect of underlying planar multilayer structures.

### A fast, high-order algorithm for the solution of surface scattering problems: basic implementation, tests, and applications
