The amplitude factors Ei** and E2** have been defined in such a way as 

 to reflect the principal effects of attenuation difference in the two lines; 

 for the case in which the driven line attcnual ion constant ai is negligible, 

 note that £"1** and E^** contain all the anii)litude variations of Ei and 

 E2 respectively. In general, Ei** and E-** are the ratios of the wave am- 

 plitudes actually present in lines 1 and 2 respectively lo the wave am- 

 plitude which would exist in lino 1 at the same value of x in the absence 

 of coupling.
