On Wellposedness and Convergence of UPML method for analyzing wave scattering in layered media
Wangtao Lu, Jun Lai, Haijun Wu
This paper proposes a novel method to establish the wellposedness and convergence theory of the uniaxial-perfectly-matched-layer (UPML) method in solving a two-dimensional acoustic…

Time-harmonic acoustic scattering from a non-locally perturbed trapezoidal surface
Wangtao Lu, Guanghui Hu
This paper is concerned with acoustic scattering from a sound-soft trapezoidal surface in two dimensions. The trapezoidal surface is supposed to consist of two horizontal half-line…
