Development and characterization of a millimeter-wave circular polarization observation method using a quarter-wave plate with Simons Array

Kana Sakaguri, Darcy R. Barron, Yuji Chinone +17

We have developed and demonstrated a method for measuring circular polarization at 90 GHz by combining a quarter-wave plate (QWP) and a continuously rotating half-wave plate (HWP).…

The 1.3 mm Full-Stokes Polarization System at CARMA

Charles L. H. Hull, Richard L. Plambeck

The CARMA 1.3 mm polarization system consists of dual-polarization receivers that are sensitive to right- (R) and left-circular (L) polarization, and a spectral-line correlator tha…
