Influence of scattering properties due to complex refractive index of ice

The relationship between complex refractive index and complex dielectric permittivity is discussed, studied variations in pure-ice complex dielectric permittivity with wavelength and temperature using the LH model. The influence of scattering properties of hexagonal ice crystals due to the change of the complex refractive index was studied using DDA at 94GHz. The results show that the relative error of scattering efficiency, absorption efficiency, asymmetry factor and backscattering efficiency does not exceed 0.24%, 0.24%, 0.09625 % and 0.83% respectively in the case of that the relative error of the real part of the complex refractive index does not exceed 0.22% while the imaginary part remain unchanged; the relative error of absorption efficiency and asymmetry factor do not exceed 1.46%, 0.2065 × 10^-4 respectively while scattering efficiency and backscattering efficiency remain constant in the case of that the relative error of the imaginary part of the complex refractive index does not exceed 1.46% whereas the real part remains unchanged.
