Abstract

The equiphase-sphere (EPS) approximation for calculating the total-scattering cross-section (TSCS) spectra of inhomogeneous microparticles having complex interior structures was analyzed. It was observed that the closed-form, analytical approximation could accurately model the TSCS of randomly inhomogeneous spherical particles having internal refractive index variation s with geometrical scales spanning from nanometers. It was also An easy-to-use criterion for the range of validity of the EPS approximation in modeling TSCS of inhomogeneous particles was also derived. It was found that the formulation in the EPS could impact tissue optical imaging and diagnostic applications.
