We have developed a finite-difference time domain (FDTD) method and a novel geometric ray-tracing model for the calculation of light scattering by hexagonal ice crystals. In the FDTD method we use a staggered Cartesian grid with the implementation of an efficient absorbing boundary condition for the truncation of the computation domain. We introduce the Maxwell–Garnett rule to compute the mean values of the dielectric constant at grid points to reduce the inaccuracy produced by the staircasing… CONTINUE READING
