Abstract

We investigate the phase matrices of droxtals at wavelengths of 0.66 and 11 μm by using an improved geometrical-optics method. An efficient method is developed to specify the incident rays and the corresponding impinging points on the particle surface necessary to initialize the ray-tracing computations. At the 0.66-μm wavelength, the optical properties of droxtals are different from those of hexagonal ice crystals. At the 11-μm wavelength, the phase functions for droxtals are essentially featureless because of strong absorption within the particles, except for ripple structures that are caused by the phase interference of the diffracted wave.
