The complex amplitude ratios for light are defined as:
rTM = ErTM / EiTM
tTM = EtTM / EtTM
I've done the derivation from Wikipedia and see that
(n2/n1) * tTM = rTM + 1.
But I don't understand what is going on physically. I understand that these values are not power or intensity so I can't really invoke conservation of energy (or can I?). Why is
r + 1 = t
for TE light, but not TM?
Thanks.
