A good reference is HP's application note, AN 95-1, available for download
from Agilent: http://contact.tm.agilent.com/Agilen...5-1/index.html

Another good reference is: _Fields_and_Waves_... by Ramo, Whinnery, and
Van Duzer, section 11.09. The basic equations are pretty simple:

b1 = s11*a1 + s12*a2 b2 = s21*a1 + s22*a2
