Radial complex scaling for anisotropic scalar resonance problems
Martin Halla
The complex scaling/perfectly matched layer method is a widely spread technique to simulate wave propagation problems in open domains. The method is very popular, because its imple…

On the treatment of exterior domains for the time-harmonic equations of stellar oscillations
Martin Halla
In a recent article we started to analyze the time-harmonic equations of stellar oscillations. As a first step we considered bounded domains together with an essential boundary con…

On the approximation of dispersive electromagnetic eigenvalue problems in 2D
Martin Halla
We consider time-harmonic electromagnetic wave equations in composites of a dispersive material surrounded by a classical material. In certain frequency ranges this leads to sign-c…
