Abstract The scattering characteristics of terahertz wave by a spherical particle are studied in this paper. A model, which can uniformly describe the expansion coefficients of uncharged, evenly charged and partially charged conditions, is developed and verified. The results of numerical calculation manifest that the scattering of terahertz wave is enhanced, whenever the particle is evenly or partially charged in the given frequency range, particle radius and the surface charge densities, compared with the uncharged case. Moreover, it is also found that the scattering of terahertz wave is basically monotonously enhanced if the particle is negatively charged; and it is basically non-monotonously enhanced if the particle is positively charged. Besides, the terahertz wave’s 3-D scattering field intensity distributions of uncharged, evenly charged and partially charged conditions are compared. In a word, this study is crucial to discuss the feasibility of terahertz wave communication technology in the complicated environment with charged particles. In addition, the potential application of this study in biomedical field is also proposed.
