摘要：

We deduced the scattering phase function (SPF) of a charged spherical particle, which is significantly different from the SPF of an uncharged spherical sphere. The difference between the SPF of a charged spherical particle and the SPF of an uncharged spherical sphere is related to the surface conductivity, particle size parameter, frequency of the electromagnetic (EM) waves, and refractive index of the particle. The surface charges carried by the particle make the backward scattering of EM waves increase. Given the EM wave frequency and the refractive index, there is a threshold of surface conductivity for each particle size number, beyond which the SPF mainly depends on the surface conductivity.
