Demonstrates asymmetric optical behavior in dielectric metasurfaces, revealing implications for light manipulation.
A pair of coupled spheres, representing two opposite symmetry resonances, illustrates the strong electromagnetic mode interaction driving reciprocal bianisotropy in a dielectric metasurface. Their Rabi-like hybridization enables strikingly asymmetric optical behavior in a dual-band setting: near-total reflection for illumination from one side and near-perfect absorption from the opposite direction, revealing the interplay between symmetry breaking, mode coupling, and directional light dissipation. More details can be found in the Research Article by Luis Manuel Máñez-Espina and co-workers (DOI: 10.1002/nap2.70145).
