REACTIONAL TORQUE OF RADIATING ELECTRIC CURRENTS.

A theoretical investigation is made of the realtion between radiated power and reactional torque of both infinitely long electric line sources and dipole antennas. Since the reactional torque is caused by the interaction between at least two sources, arrangements of two line sources or two dipoles are considered throughout. The possible influence of a supporting structure, approximated by a conducting circular cylinder, is examined. The advantage of adding more sources to the configuration is also discussed. It is shown that for the assumed configurations the torque to power ratio can be maintained almost independent of frequency, which may have considerable practical significance.
