Hi, 

I have a question concerning using mathematica to draw
the cross-sectional pattern of the polarisation
ellipse.

I want to know how I would draw an ellipse, in the XY
plane, with propagation in the positive z-direction,
by specifying its 
- azimuth (angle that the major axis of the
cross-sectional ellipse makes with the horizontal
x-axis (positive when counterclockwise from x-axis)) 
- ellipticity (measure of the fatness of the ellipse,
(ratio of the lengh of the semi-minor axis to that of
the semi-major axis))


Thanks
Caroline
