论文摘要
在本文中，我们提供了针对一般高对比度3D介电的一般渐近散射共振公式的进一步频谱分析，该公式最初得出了一阶近似值。为了研究此类共振的完全膨胀的成分，针对高对比度纳米球的情况提出了故障。对于径向对称场，我们还得出了一个准确的共振公式，用于球形散射器的半径，不一定很小且介电敏感性系数，不一定高。公式可用于成像应用程序，可从频率测量中识别对象的属性。在高对比度纳米球的情况下，后一种公式将进一步开发和简化。
In this paper we provide further spectral analysis of the general asymptotic scattering resonances formula of small high contrast 3D dielectrics of arbitrary shape, initially derived to a first order approximation. To investigate the components of a full expansion of such resonances, a breakdown is presented for the case of high contrast nanospheres. We also derive, for radially symmetric fields, an exact resonance formula for a spherical scatterer in terms of its radius, not necessarily small, and dielectric susceptibility coefficient, not necessarily high. Formula that is useful in imaging applications to identify objects' properties from frequency measurements. The latter formula is further developed and simplified in the case of high contrast nanospheres.
