Physical Optics Analysis of Polarization Effects in SO LAT Reflectors
Xiaodong Ren, Patricio A. Gallardo, Jon E. Gudmundsson
We present a physical-optics analysis of the polarization response of the reflective optical of the Simons Observatory Large Aperture Telescope (SO LAT). Far-field co-polar and cro…

Polarization rotation through differential transmission in refractive CMB telescopes identified using a hybrid physical optics method
Xiaodong Ren, Rustam Balafendiev, Jon E. Gudmundsson
We identify a polarization rotation systematic in the far field beams of refractive cosmic microwave background (CMB) telescopes caused by differential transmission in anti-reflect…
