  The goal of the PolarKID project is testing a new method for the measurement
of polarized sources, in order to identify all the possible instrumental
systematic effects that could impact the detection of CMB B-modes of
polarization. It employs the KISS (KIDs Interferometer Spectrum Survey)
instrument coupled to a sky simulator and to sources such as point-like black
bodies (simulating planets), a dipole (extended source) and a polarizer. We use
filled-arrays Lumped Element Kinetic Inductance Detectors (LEKIDs) since they
have multiple advantages when observing both in a photometry and in a
polarimetry configuration
