An analytic solution to the scattering of the zero-order Bessel beam by a spheroidal particle is constructed on the basis of the generalized Lorenz–Mie theory (GLMT). The spheroidal beam shape coefficients (BSCs) of the zero-order Bessel beam are directly expressed in spheroidal coordinates and computed conveniently using an intrinsic method. Utilizing the tangential continuity of the electromagnetic...
Within the framework of the generalized Lorenz–Mie theory (GLMT), scattering from a homogeneous spheroidal particle illuminated by an on-axis Gaussian beam is formulated analytically, with more attention paid to the investigation of internal and near-surface fields. Numerical results concerning the spatial distributions of internal and near-surface fields are presented. This study may be useful to...
