粒子共振光散射的瞬态效应：Anapole作为“冻结光”的存储器？
Transient effects at resonant light scattering by particles: Anapole as a storage for "frozen light"?
摘要：
本文讨论了激光脉冲前沿高Q共振模激发的瞬态效应及其在脉冲被粒子散射过程中在脉冲后沿的分解。主要的注意力是支付给nonradiating（anapole）模式激发在高指数圆柱。这个问题进行了研究分析和数值。结果表明，再极点是一个稳定的，但本质上是非平衡的模式，它可以存在，当且仅当主机粒子被照射的连续入射波。一旦入射波被切断，阿那普尔就变成辐射模式，并且由于广泛的辐射损失而非常快地崩溃。它破坏了利用类似阿纳普尔的激发作为“冻结光”存储器的希望。"
英文摘要：
Transient effects at excitation of high-Q resonant modes at a leading front of a laser pulse and their decomposition at its trailing edge during the pulse scattering by a particle are discussed. The main attention is paid to the nonradiating (anapole) mode excited in a high-index cylinder. The problem is studied both analytically and numerically. It is shown that the anapole is a steady but essentially nonequilibrium mode, which can exist if and only if the host particle is irradiated by a continuous incident wave. As soon as the incident wave is switched off the anapole becomes a radiating mode and collapses very fast owing to extensive radiative losses. It ruins the hopes to employ the anapole-like excitations as storages for the "frozen light."
