Computing Maxwell eigenmodes with Bloch boundary conditions
Steffen Börm, Ralf Köhl, Nahid Talebi
Our goal is to predict the band structure of photonic crystals. This task requires us to compute a number of the smallest non-zero eigenvalues of the time-harmonic Maxwell operator…

Topological photonics by breaking the degeneracy of line node singularities in semimetal-like photonic crystals
Steffen Börm, Fatemeh Davoodi, Ralf Köhl +1
Degeneracy is an omnipresent phenomenon in various physical systems, which has its roots in the preservation of geometrical symmetry. In electronic and photonic crystal systems, ve…
