Circular polarization phase difference

Click For Summary

Discussion Overview

The discussion revolves around the phase difference required for circular polarization of electric field vectors. Participants explore the relationship between phase difference and the multiples of 90 degrees, questioning the values substituted in calculations.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion regarding the phase difference for circular polarization, suggesting it should be odd multiples of 90 degrees but encounters issues when substituting values of n.
  • Another participant asks for clarification on which n value was substituted, indicating a need for specificity in calculations.
  • A participant references a textbook that states multiples of 90 degrees are required for circular polarization, but they are unable to achieve this through their substitutions.
  • There is a clarification that 90 degrees corresponds to π/2, which is relevant to the discussion of phase differences.
  • One participant explains that +90 degrees corresponds to clockwise (CW) and -90 degrees to counterclockwise (CCW), affirming that odd multiples of 90 degrees can be valid representations of circular polarization.
  • A participant acknowledges a mistake in their calculations, indicating a resolution to their confusion.

Areas of Agreement / Disagreement

The discussion reflects some disagreement regarding the correct interpretation of phase differences for circular polarization, with multiple viewpoints on the values of n and their implications. However, one participant resolves their confusion by recognizing a mistake in their approach.

Contextual Notes

Participants reference specific values of n and their substitutions, but the discussion does not clarify the assumptions or definitions used in these calculations, leaving some ambiguity in the reasoning.

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..
