Abstract:
There has been a constant improvement in the observational measurement of linear polarization in chromospheric
spectral lines in the last three decades. However, modeling polarized profiles of these lines still remains incomplete,
due to the lack of inclusion of fundamental physics in modeling efforts. To model the observed solar spectrum and
its linear polarization, we need a solution to the polarized radiative transfer equation. The polarization in strong
resonance lines originates from the scattering mechanism known as the partial frequency redistribution (PFR) of an
anisotropic radiation field. The understanding of the linear polarization in spatially resolved structures needs
radiative transfer solutions in multidimensional geometries. In this paper, we explore the effects of angle-dependent
PFR on scattering polarization profiles formed in three-dimensional (3D) media. We find that the 3D geometry
combined with angle-dependent PFR produces more scattering polarization than an angle-averaged one.
