title: Effects of bump/pit on the radiative properties of small particles.
abstract: We use the particle superposition model to create bumps or pits on the surface of small particles for the purpose of simulating the roughness of the particles. Four different models are introduced to show the bump/pit effect on the radiative properties of the host particle. The results show that surface roughness plays an important role in the light scattering properties of small particles. Different roughened models behave differently.
