Description

Future satellite missions focusing on the tensor-to-scalar ratio r will likely include a rotating half-wave plate (HWP) device in order to precisely recover the B-mode polarization signal. Patanchon [2023] modeled the effect of HWP systematic imperfections leading to Intensity to Polarization (IP) leakage on the measurement of the B-mode signal. This model is now implemented in the LiteBIRD Simulation Framework (LBS), a comprehensive simulation framework developed for the data acquisition from the LiteBIRD spacecraft.
