Lorentz-Mie

Direct calculations using the Lorentz Mie theory for spherical particles show that the surfaces of constant phase of the total field are funnel-shaped in the vicinity of the particle (Fig. 5). Such near-field properties are typical for spherical particle with other size and refractive index [26,28]. 

Figure 5 Radiative properties of Chlamydomonas reinhardtii (ieft) and Rhodospirillum rubrum (right) obtained with the volume equivalent sphere approximation and a Lorentz-Mie code (gray color) and with a more accurate description of the shape and Schiff s approximation (black color) a prolate spheroid with elongation 1.2 (aspect ratio 0.837) for C. reinhardtii and a cylinder with elongation 3.8 (aspect ratio 0.263) for Rs. rubrum. These results were obtained by implementing the methodological chain presented in Section 2.1 for a log-normal size distribution pf, (reg =...

Lorentz-Mie region. When m > 1 and d is comparable to A, - the case for most latex systems - the full Lorentz-Mie theory must be employed. The scattered intensity ratio I/Iq is then given by,...
