Scaled analog measurements of light scattering by aggregates with merging monomers

Abstract

This work reports on the experimental analysis of light scattering by aggregates with merging monomers. For such complex shape particles, scaled targets can be built using a rapid prototyping technique (stereo lithography). Our microwave scattering device provides the amplitude and phase of elements of the amplitude scattering matrix. Assessment of the approximate codes can thus be carried out on an exprimental basis. Sample results for the bi-sphere and a 74 sphere aggregate are presented and discussed.
