From: Directional amplitude backscatter modulation with suppressed Doppler based on rotating resonant loop
Backscatter communication based on rotating scatterers with (a) pure Doppler modulation, (b) pure polarization modulation, and (c) pure DAM. (d,e) backscatter communication with combined DAM and Doppler modulation. The phase change of the induced current on the scatterer during the rotation in (d,e) is shown by two red dots for normal incidence, and one blue and one green dot for oblique incidence.
