Abstract

Energy flows in polychromatic fields are considered. It is shown that for fields obtained as a result of the superposition of two waves with different frequencies with an analysis time shorter than the beat period, the behavior of the characteristics of the Poynting vector and angular momentum depend on the intermodulation components of the instantaneous vector. The Stokes parameters in this case determine not the state of polarization, but rather the value of the spin angular momentum. The magnitude of the Poynting vector modulus depends on the structure of the analyzed field and for fields of general form is at a level of 20% of the value observed for a coherent wave. Computer simulation data are presented.
