In this paper, we design c-Si nanodisk Mie resonators based on the dipole modes. By changing the geometry, the enhanced field extends outside the resonators and the sensitivity is improved. The sensitivity of the magnetic dipole mode is up to 365 nm/RIU, which is greater than the previously reported sensitivity of the electric dipole mode-based Mie resonators.
