Abstract

A polarimeter includes an integrated device with an array of antennas including multiple column pairs. Each column pair has two columns, and each column in each column pair includes multiple antennas. A first column of each column pair in the array scatters a first polarization component of an incident radiation, and a second column of each column pair in the array scatters a second polarization component of the incident radiation. The scattered fields of the column pairs interfere constructively in a direction depending on the polarization of the incident radiation, resulting in maximal intensity at a certain point in space for a specific polarization state. Multiple column pairs in parallel and oriented at angles with respect to each other can be used to scatter different polarization components of the incident radiation directionally to different points in space. Detectors are positioned with respect to the integrated device to detect polarization components.
