-At EOVSA’s linear feeds, in the electric field the linear polarization, X and Y, relates to RCP and LCP (R and L) as:
-:<math> R = X + iY </math>
-:<math> L = X - iY </math>
-In terms of autocorrelation powers, we have the 4 polarization products XX*, YY*, XY* and YX*, where the * denotes complex conjugation.  The quantities RR* and LL* are then
-:<math> RR^* = (X + iY)(X + iY)^* = XX^* - iXY^* + iYX^* +YY^* </math>
