The basis of the particle size determination is the idea that the sum of intensities of the scattered light in all scattering angles PAM/IDA scattering stage detectors is nearly independent of particle composition, shape, and internal structure but sensitive to the particle size. This idea was checked with theoretical calculations for spherical particles and with microwave analog experiments for aggregated particles. Figure 2 shows how the idea works. io*1
