Latent Su-Schrieffer-Heeger models
Malte Röntgen, Xuelong Chen, Wenlong Gao +5
The Su-Schrieffer-Heeger (SSH) chain is the reference model of a one-dimensional topological insulator. Its topological nature can be explained by the quantization of the Zak phase…
Equireflectionality and customized unbalanced coherent perfect absorption in asymmetric waveguide networks
Malte Röntgen, Olivier Richoux, Georgios Theocharis +4
We explore the scattering of waves in designed asymmetric one-dimensional waveguide networks. We show that the reflection between two ports of an asymmetric network can be identica…
Covert Scattering Control in Metamaterials with Non-Locally Encoded Hidden Symmetry
Jérôme Sol, Malte Röntgen, Philipp del Hougne
Symmetries and tunability are of fundamental importance in wave scattering control, but symmetries are often obvious upon visual inspection which constitutes a significant vulnerab…
