Suppose I have an eliptically polarizied EM wave, whose electric field can be written as

[tex]\vec{E}=A\cos(kz-\omega t)\vec{e}_x+B\sin(kz-\omega t)\vec{e}_y,[/tex]

where the constants [itex]A[/itex] and [itex]B[/itex] are amplitudes of the [itex]x[/itex] and [itex]y[/itex] components of the beam, respectively.

How would I report the amplitude of the whole beam?

(Please note that I am not looking for

[tex]\vec{E}=A\cos(kz-\omega t)\vec{e}_x+B\sin(kz-\omega t)\vec{e}_y,[/tex]

where the constants [itex]A[/itex] and [itex]B[/itex] are amplitudes of the [itex]x[/itex] and [itex]y[/itex] components of the beam, respectively.

How would I report the amplitude of the whole beam?

(Please note that I am not looking for

*intensity*of the beam -- I know how to report that).
