Superscattering engineering through combined resonant modes
Introduction The scattering of light by small particles is a fundamental problem in modern optics, dating back to Rayleigh’s work on atmospheric scattering ( Rayleigh, 1871; Rayleigh, 1871). The strength of the light-matter interaction is usually characterized by the scattering cross section.

Backscattering Reconfigurable Superscatterers Based on Plasma-Metasurface Structure
Result (a)(b) Far-field scattering patterns of two states reconfigured by regulate plasma density. (a) Strongly backscattering state. (b) Scattering cancelling state. Conclusion Due to the weak optical response properties of tiny objects, it is difficult to modulate light at subwavlength scales.
