The sensitivities of the effective refractive index to any change in the refractive index/thickness of the adlayer are derived and studied with the parameters of the LHM. It is found that a slight change in the real parts of the permittivity and permeability of the LHM can significantly improve the sensitivity of the proposed sensor. popup.nrat_date 2025-03-24 Close
