Termination-Driven Control over BIC Q-Factors and Frequencies in Plasmonic Double Net Metamaterials
Cedric Schumacher, Bilel Abdennadher, Ullrich Steiner +1
Interlaced metallic wire meshes are 3D metamaterials consisting of two intertwined metallic networks. These plasmonic double nets give rise to otherwise unobserved longitudinal, we…

Anoplophora graafi Longhorn Beetle Coloration is due to Disordered Diamond-like Packed Spheres
Kenza Djeghdi, Cedric Schumacher, Ilja Gunkel +2
While artificially photonic materials are typically highly ordered, photonic structures in many species of birds and insects do not possess a long-range order. Studying their order…

Metamaterial Eigenmodes beyond Homogenization
Antonio Günzler, Cedric Schumacher, Matthias Saba
Metamaterial homogenization theories usually start with crude approximations that are valid in certain limits in zero order, such as small frequencies, wave vectors and material fi…
