Preasymptotic error estimates of higher-order EEM for the time-harmonic Maxwell equations with large wave number
Shuaishuai Lu, Haijun Wu
The time-harmonic Maxwell equations with impedance boundary condition and large wave number are discretized using the second-type Nédélec's edge element method (EEM). Preasymptot…

An Unfitted Interface Penalty DG--FE Method for Elliptic Interface Problems
Juan Han, Haijun Wu, Yuanming Xiao
We propose an unfitted interface penalty Discontinuous Galerkin-Finite Element Method (UIPDG-FEM) for elliptic interface problems. This hybrid method combines the interior penalty…
