A boundary integral equation method for wave scattering in periodic structures via the Floquet-Bloch transform
Wangtao Lu, Kuanrong Shen, Ruming Zhang
This paper is concerned with the problem of an acoustic wave scattering in a locally perturbed periodic structure. As the total wavefield is non-quasi-periodic, effective truncatio…

Parallel overlapping-domain decomposition FDFD for large-scale complex nanostructures modeling
Zhanwen Wang, Chengnian Huang, Wangtao Lu +2
The increasing complexity and scale of photonic and electromagnetic devices demand efficient and accurate numerical solvers. In this work, we develop a parallel overlapping domain…
