Poynting vector

xnoiz

In case of a circularly polarized wave, is the poynting vector also circularly polarized?

If not what happens in this case?

Dickfore

no, the poynting vector is directed in the direction of propagation.

One difference is that for a uniform linearly polarized wave, magnitude of Poynting vector fluctuates periodically between zero and maximum at twice the wave frequency. For a similar circularly polarized wave there is no fluctuation in net power.
