Fog is a collection of micro drops of water suspended in the air, formed as a result of cooling of moist air. In supercooled air, water droplets freeze, forming ice fog at air temperatures below - 10-15° C. As the ice drop freezes, it forms a core-shell structure. In such a particle, a high-Q Fano resonance is possible, which entails the formation of a magnetic pulse. Our theoretical calculations have predicted the time-dependent formation of Fano resonances in a freezing the outside in water droplet. Time-varying unconventional Fano resonance with magnetic field enhancement yield new method to manipulate light-matter interactions in a freezing water droplet. To the best of our knowledge this mechanism was not discussed previously.
雾是悬浮在空气中的微小水滴的集合体，是潮湿空气冷却形成的。在过冷空气中，水滴会结冰，在气温低于-10至-15摄氏度时形成冰雾。随着冰滴冻结，会形成核壳结构。在这样的粒子中，可能会出现高Q值的法诺共振，这会导致磁脉冲的形成。我们的理论计算预测了在水滴从外部开始冻结过程中法诺共振随时间的形成。具有磁场增强的随时间变化的非常规法诺共振产生了一种在冻结水滴中操纵光与物质相互作用的新方法。据我们所知，这种机制以前没有被讨论过。
