3. Polarimeters and the calibration The polarization state of a wave incident on a polarizer in front of the first amplification stage of a receiver can be described by two circular components. Following Kraus (1966), these components can be expressed as: where r,l represent the electric vector amplitude of each of the circularly polarized components, and their relative phase.
