Abstract :
Metasurfaces made of intertwined spiral arrays on in-plane magnetized ferrite substrates are investigated for both normal and oblique incidence of linear polarized waves. The simulation results evidence that the fundamental topological resonance co-exists with the transverse ferromagnetic resonance of ferrite substrate. Effects of near-field hybridisation combined with Cotton-Mouton effects or Faraday rotation are also discussed in connection to the topological resonance and its fractional bandwidth.
