Abstract

This study examines the polarization retention of linearly polarized light during forward transmission through concentric spherical microparticles. By using silica-encapsulated water and oil-encapsulated water-encapsulated silica as examples, the study explores the effects of wavelength, particle size, refractive index variations, different distributions, and double/triple-layered spheres on polarization retention in forward transmission. The research identifies polarization-preserving channels at specific wavelengths. Polarization retention characteristics vary with particle size. For silica-encapsulated water spheres with radii of 1μm, 2μm, 5μm, 10μm, and 20μm, distinct intervals exhibit rapid declines in polarization retention. In contrast, silica-encapsulated water spheres with radii of 0.2μm and 0.5μm show no intervals of rapid polarization retention decline. Each silica-encapsulated water sphere exhibits a unique depolarization interval under varying refractive index conditions. As the forward transmission angle increases under different distributions, superior polarization retention characteristics shift from monodisperse to normal and log-normal distributions. For double-layered and triple-layered concentric spherical microparticles, both silicaencapsulated water and oil-encapsulated water-encapsulated silica exhibit distinct depolarization intervals.
