question: What happens to the polarization state when the axially rotated scatterer switches from left-handed (right-handed) circular polarization to right-handed (left-handed) circular polarization under the circular basis? option 1: The polarization state remains the same option 2: The polarization state switches to linear polarization option 3: The polarization state switches to dual-linear polarization option 4: The polarization state switches to left-handed (right-handed) circular polarization option 5: None of the above
