(a) Schematics of the polarization sensing detector using slot antennas coupled to bolometer loads. Antenna 1 receives the maximum power when the incident beam has an electric field in the plane of ϕ = 135° and ϕ = 315° and Antenna 2 has the maximum absorption when the electric field is in the plane of ϕ = 45° and ϕ = 225°. (b) The behavior of bolometer loads in the orthogonal antennas during the polarization sensing process. The red glows around the bolometers represent the temperature of each bolometers. Higher intensity glow indicates higher temperatures. At polarization angle of zero, bolometers of both antennas receive equal amounts of power. The temperature of bolometers in slot antenna 1 (2) are higher when the polarization angle is −45° (45°).
