# Circular polarization phase difference

Phase difference between two component of Electric field vector seems to me that the phase difference for circular should be of odd multiples of 90 but its not 90 when n value substituted. Please help for solution..

Which n value did you substitute?

my doubt is.... as per the textbook i am referring there should be multiples of 90 degree of phase difference is required for circular polarization but here even after substituting all possible values of n= 0,1,2,3,..... I couldn't get multiple of 90... then how can it be the representation of circular polarization phase difference??

You do realize that 90° = $\pi$ / 2 ?

it is +90 deg = +pi/2 for CW=clockwise and
-90deg = -pi/2 for CCW= counter clockwise.

-90 + 360 = 270 = 3*90, so yes, it is odd multiples of 90deg as long as you don't care if it is left-handed or right-handed circular polarization.

i got it... I was doing silly mistake substituting wrong value...
Thanks..
