Design and Performance of a 30/40 GHz Diplexed Focal Plane for the BICEP Array

The Astrophysical Journal Supplement Series
We demonstrate a wideband diplexed focal plane suitable for observing low-frequency foregrounds that are important for cosmic microwave background polarimetry.

QUIJOTE-TFGI polarization calibration

Astronomy & Astrophysics
Context. Polarization measurements in the 30–40 GHz range are essential to improving our understanding of Galactic synchrotron radiation and potential anomalous microwave emissions, and obtaining such measurements will ultimately aid in detecting ...

Optimal Summary Statistics for X-ray Polarization

The Open Journal of Astrophysics
We develop two new highly efficient estimators to measure the polarization (Stokes parameters) in experiments that constrain the position angle of individual photons such as scattering and gas-pixel-detector polarimeters, and analyse in detail a ...

Extended Eigenvalue Calibration Method With Joint Optimization for Overdetermined Mueller Matrix Polarimeters

IEEE Photonics Journal
In Mueller matrix polarimetry, the accuracy of polarimeter calibration directly determines the reliability of measurement results. As a general calibration method, the eigenvalue calibration method (ECM) is widely adopted since it does not require exact ...
