摘要

一方面，我们考虑了两种t矩阵理论，即“广义Lorenz-Mie理论”（GLMT）和“扩展边界条件法”（EBCM），其中结构梁可以在矢量球面波函数（vswf）上展开，膨胀系数用电磁波束形状系数（BSCs）表示。另一方面，我们考虑声学（更普遍的标量）场，这些场可以通过对基本函数的展开类似地表示，膨胀系数使用声学（标量）BSCs表示。我们建立了电磁和标量BSCs之间的关系。

On a relationship between acoustical (more generally scalar) beam shape coefficients and electromagnetic beam shape coefficients of some T-matrix theories for structured beams

On one hand, we consider two T-matrix theories, namely “Generalized Lorenz–Mie theory” (GLMT) and “Extended Boundary Condition Method” (EBCM), in which structured beams may be expanded over Vector Spherical Wave Functions (VSWFs), with expansion coefficients expressed by using electromagnetic Beam Shape Coefficients (BSCs). On the other hand, we consider acoustical (more generally scalar) fields which may be expressed similarly by an expansion over basic functions, with expansion coefficients expressed using acoustical (scalar) BSCs. We establish relationships between electromagnetic and scalar BSCs.
