Hi Guys I have a very simple and basic question. Assume interface of two dielectric mediums. If the t is transmition cofficient for electricfield from medium 1 to medium 2 with refractive indexs n1 and n2, what is the transmitivity of power from medium 1 to medium 2? I know it is n2/n1*t2. But wouldn't you expect it to be (n1/n2)2*t2 because the elecromagnetic energy is defined as epsilone*E2 which is the same as n2E2?
