    Photonic time crystals often require high modulation depths of material properties to exhibit large momentum bandgaps. We show that such a requirement can be dramatically relaxed by exploiting the structural resonances of a spatiotemporal metasurface.
  • Scattering of light by spheres made from a time-modulated and dispersive material
    (2021-09-20) Ptitcyn, G.; Lamprianidis, A.; Karamanos, T.; Muller, M.; Alaee, R.; Asadchy, V. S.; Mirmoosa, M. S.; Albooyeh, M.; Fan, S.; Rockstuhl, C.; Tretyakov, S. A.

    We derive the dispersion relation of eigenmodes propagating in a time-varying and dispersive medium. We use these eigenmodes to analytically study the scattering of light by a sphere made from a time-varying and dispersive medium. These results are compared to full-wave optical simulations and excellent agreement is observed. With that, we provide tools and outline a path towards further explorations of light scattering by time-varying finite particles.
