In plane wave elliptical polarization, the book said if the Ellipticity angle is possitive, it is a Left Hand Circular polarization(LHC). If Ellipticity angle is negative, it is Right Hand Circular polarization(RHC).
My question is how can Ellipticity angle be negative?
http://en.wikipedia.org/wiki/Polarization_%28waves%29
Can anyone show a picture of negative Ellipticity angle?
In case this sounds ridiculous, attached is the scan of the paragraph from the "Engineering Electromagnetics" by Ulaby. I have to scan in two part to fit the size limit. First is Ulaby1 and then Ulaby2.
Thanks
