摘要：

Based on the generalized Lorenz-Mie theory (GLMT), the incident Gaussian beam and scattered fields of the chiral sphere are expressed in terms of the spherical vector wave functions. An expression of the radiation force on the chiral sphere in a Gaussian beam is derived from the theory of electromagnetic momentum. The influence of the chiral parameter, the beam waist radius and the radius of the chiral sphere on radiation force is discussed numerically.
