Morphology-dependent resonances in a coated sphere are investigated by computation of the volumeaveraged source function obtained from Lorenz-Mie theory. Analytic expressions for the source function in absorbing and nonabsorbing spheres are given in a suitable form for computations. An advantage of the investigation of the source function is that core and shell contributions can be computed and examined independently. Furthermore the influences of the refractive index and the thickness of the outer layer on resonance positions and height are studied in detail. These influences are presented for the α(104) partial-wave example.
通过计算从洛伦兹 - 米氏理论获得的体积平均源函数，研究了涂层球体中形态依赖的共振。给出了吸收和非吸收球体中源函数的解析表达式，其形式适合计算。研究源函数的一个优点是可以独立计算和检查核心和壳层的贡献。此外，还详细研究了外层折射率和厚度对共振位置和高度的影响。以α(104) 分波为例展示了这些影响。
