The radiation force of highly focused cosine-Gaussian beam acting on a particle in the Rayleigh scattering regime is theoretically investigated in this paper. The results show that it is feasible to utilize cosine-Gaussian beam in optical trapping system. Unlike the conventional optical beams, the cosine-Gaussian beam could simultaneously trap particles whose refractive index is lower or higher than the ambient.
