Mie theory

Extreme scattering phenomena, such as nonreciprocity, and parametric amplification, in periodically time-varying mediums have attracted numerous attentions in recent years. Periodically time-varying permittivity is used as an additional degree of freedom in metamaterials or metasurfaces. Here, we investigate the Floquet Mie scattering properties of a spherical nanoparticle coated with a time-varying dispersive shell. Our result can provide insight into the light-matter interaction in the time-varying system and can also guide the antenna design based on the core-shell structure.
