By the model equations, we examined numerical results using the first-order (dependent) scattering theory (FST) and radiative transfer theory in 600-980 nm wavelength. The model equations efficiently treat the interference of electric fields scattered from colloidal particles by a single effective coefficient, providing fast computation. Meanwhile, the FST provides accurate but complicated treatment. We found the interference effects on the scattering properties and characteristic time depend linearly on wavelength. Dimensionless analysis showed a simple mechanism of the interference effects, independently of wavelength and source-detector distance.OSA2022-01-31engjournal articleVoRhttp://hdl.handle.net/2115/83934https://doi.org/10.1364/OE.4473341094-4087Optics Express30335383552https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/83934/1/oe-30-3-3538.pdfapplication/pdf2.86 MB2022-01-31
