Convergence of the PML-BIE Method for Acoustic Scattering in an Impedance Half-Space
Wangtao Lu
The perfectly matched layer-based boundary integral equation (PML-BIE) method (Lu et al., \emph{SIAM J. Appl. Math.} 78 (2018)) has become an effective tool for wave scattering pro…
Existence of Friedrich-Wintgen Bound States in the Continuum: Cavity with a Thin Waveguide Opening
Jiaxin Zhou, Wangtao Lu, Ya Yan Lu
Bound states in the continuum (BICs) are localized states embedded within a continuum of propagating waves. Perturbations that disrupt BICs typically induce ultra-strong resonances…
On exact truncation of backward waves in elastrodynamics
Wangtao Lu
For elastic wave scattering problems in unbounded anisotropic media, the existence of backward waves makes classic truncation techniques fail completely. This paper is concerned wi…
A highly accurate perfectly-matched-layer boundary integral equation solver for acoustic layered-medium problems
Wangtao Lu, Liwei Xu, Tao Yin +1
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 defect…
Parametric dependence of bound states in the continuum: a general theory
Amgad Abdrabou, Lijun Yuan, Wangtao Lu +1
Photonic structures with high- resonances are essential for many practical applications, and they can be relatively easily realized by modifying ideal structures with bound stat…
Mathematical theory for electromagnetic scattering resonances and field enhancement in a subwavelength annular gap
Junshan Lin, Wangtao Lu, Hai Zhang
This work presents a mathematical theory for electromagnetic scattering resonances in a subwavelength annular hole embedded in a metallic slab, with the annulus width . The…
