Follow the conventional Yagi-Uda antenna, three different rings are named as director, driven element and reflector respectively in this paper.
The stimulus-to-velocity profile of this actuation is similar to that of familiar DC servomotors, but the prominent deadband in the actuation profile means that the device holds the driven element with nanoscale stabilities when quiescent.
