ABSTRACT:
An electrically-conductive flexible probe is mounted within a wave guide that receives radio-frequency electromagnetic radiation. A leading portion of the probe has an orientation that is adjustable between two positions that are angularly displaced with respect to each other by 90.degree.. A permanent bar magnet is connected to the leading portion of probe, and an electromagnet is mounted adjacent to the bar magnet so as to be capable of being magnetically coupled to the bar magnet. The electromagnet is electrically controllable so as to control the magnetic coupling between the bar magnet and the electromagnet, move the bar magnet selectively to one of the two angular positions, and thereby correspondingly move the leading portion of the probe and cause the wave guide to transmit radio-frequency electromagnetic radiation having a selected one of two polarizations in planes that are mutually orthogonal with respect to each other and reflect radio frequency electromagnetic radiation having the other polarization.
