We present both experimental data and theoretical solutions to evaluate the scattering of light and other electromagnetic radiation by complex dust morphologies. This includes porous particles made of spherical subparticles to represent aggregated structures that may be relevant models of comet dust and dust in the atmospheres of Titan and Saturn. Solid cubes represent some asteroid dust and dust in some planetary atmospheres. The experimental data were obtained in the microwave analogue to light scattering facility at the Laboratory for Astrophysics, University of Florida.
