论文摘要
我们回顾了电磁多物的计算三种不同的方法，即笛卡尔原始多物，笛卡尔不可候选多物和球形多物。我们将后者确定为最适合描述电磁辐射的散射，这是无定形硅球的例证。然后，这些多物用于计算作用在宽波长范围内的半导体，介电或金属颗粒上的光学力，从偶极向下到MIE态度。
We review three different approaches for the calculation of electromagnetic multipoles, namely the Cartesian primitive multipoles, the Cartesian irreducible multipoles and the spherical multipoles. We identify the latter as the best suited to describe the scattering of electromagnetic radiation, as exemplified for an amorphous silicon sphere. These multipoles are then used to calculate the optical force acting on semiconductor, dielectric or metallic particles in a wide wavelength range, from the dipolar down to the Mie regimes.
