Stability Analysis for Electromagnetic Waveguides. Part 1: Acoustic and Homogeneous Electromagnetic Waveguides
Jens Markus Melenk, Leszek Demkowicz, Stefan Henneking
In a time-harmonic setting, we show for heterogeneous acoustic and homogeneous electromagnetic wavesguides stability estimates with the stability constant depending linearly on the…

Wavenumber-explicit -FEM analysis for Maxwell's equations with transparent boundary conditions
Jens Markus Melenk, Stefan Sauter
The time-harmonic Maxwell equations at high wavenumber are discretized by edge elements of degree on a mesh of width . For the case of a ball and exact, transparent boun…
