Transfer of orbital angular momentum on a macroscopic object in the UHF frequency band

Résumé

We report on the exchange of orbital angular momentum between an electromagnetic microwave and a macroscopic object. Using a quadrupole wire antenna at frequency f = 870 MHz, we induce a torque on a suspended copper strip. The induced torque on the strip is of the order of 10 8 Nm. A linear dependence of the acceleration of the strip on the radiated power, up to 8.10-4 °/s², is observed and rotations of a few degrees are measured.
