Optical properties of soot aggregates with different monomer shapes

Optical properties of soot aggregates with different monomer shapes

Overview

This numerical study tests how spherical, cubic, ellipsoidal, and hexagonal-prism monomers alter the optical properties of fractal soot aggregates.

Core Contributions

• Builds fractal soot-aggregate models with four different monomer shapes.
• Computes Mueller matrices and optical cross sections using the discrete dipole approximation.
• Shows that monomer-shape effects on integral optical properties can be non-negligible when the monomers depart strongly from sphericity.
