Similar results apply to a left circular A\ave ; it is necessary only to reverse 

 the signs of o-, y in the expression for .t+ . Equations (18) and (19) show 

 that equal right and left circular incident waves emerge with tUfferent 

 amplitudes and phases; hence an incident plane polarized wave emerges 

 elliptically polarized with its major axis inclined to the polarization direc- 

 tion at incidence. The inclination and the ratio of minor to major axis
