2. Suppose space is divided into three regions, with three different indices of refrac- tion: 2<0 n = N1 0≤zd n = n2 z > d n = n3. assume that an incident plane wave is traveling in the +z direction (i.e., coming from z = −∞). The magnetic permeability is the same in all three media. Determine the transmission and reflection coefficients. In this case, the transmission coefficient is calculated for the transmitted intensity into region 3.
