Imagine E1 and E2 are signals entering inputs 1 and 2, respectively. Then outputport1 would have:

(E1+jE2)/sqrt(2)

and outputport2 would have (sqrt = square root):

(E2+jE1)/sqrt(2).

This is very simple and is true when c=0.5. c determines the percentage of power that goes from input1 to output2, or from input2 to output1. Finally, alpha is the loss coefficient, which the whole matrix is multiplied by.
