Abstract :
Electrooptic imaging of moving electric vectors has been proposed and demonstrated for the first time. Distributions of near-field polarization states over a side-fed planar spiral antenna with an infinite balun have been successfully visualized experimentally by two dimensionally arrayed arrows rotating elliptically as well as by arrayed polarization ellipses.
