Summation-by-parts approximations of the second derivative: Pseudoinverses of singular operators and revisiting the sixth order accurate narrow-stencil operator
Sofia Eriksson, Siyang Wang
We consider finite difference approximations of the second derivative, exemplified in Poisson's equation, the heat equation and the wave equation. The finite difference operators s…
Theory of the Chromatic Dispersion, Revisited
Dimitar Popmintchev, Siyang Wang, Xiaoshi Zhang +1
We derive general analytic expressions for the chromatic dispersion orders valid to infinity, due to the k vector or phase ϕ dependence on the wavelength. Additionally, we identify…
Elastic wave propagation in curvilinear coordinates with mesh refinement interfaces by a fourth order finite difference method
Lu Zhang, Siyang Wang, N. Anders Petersson
We develop a fourth order accurate finite difference method for the three dimensional elastic wave equation in isotropic media with the piecewise smooth material property. In our m…
Bridging physics-based and equivalent circuit models for lithium-ion batteries
Zeyang Geng, Siyang Wang, Matthew J. Lacey +2
In this article, a novel implementation of a widely used pseudo-two-dimensional (P2D) model for lithium-ion battery simulation is presented with a transmission line circuit structu…
