Spectral analysis and domain truncation methods for Maxwell's equations
Sabine Boegli, Francesco Ferraresso, Marco Marletta +1
We analyse how the spectrum of the anisotropic Maxwell system with bounded conductivity on a Lipschitz domain is approximated by domain truncation. First we prove a new non-convex…

Spectral properties of the inhomogeneous Drude-Lorentz model with dissipation
Francesco Ferraresso, Marco Marletta
We establish spectral enclosures and spectral approximation results for the inhomogeneous lossy Drude-Lorentz system with purely imaginary poles, in a possibly unbounded Lipschitz…
