Question

In Figure 12.5, let regions 2 and 3 both be of quarter-wave thickness. Region 4 is glass, having refractive index, n4 = 1.45; region 1 is air. (a) Find (b) Find (c) Specify a relation between the four intrinsic impedances that will enable total transmission of waves incident from the left into region 4. (d) Specify refractive index values for regions 2 and 3 that will accomplish the condition of part (c). (e) Find the fraction of incident power transmitted if the two layers were of half-wave thickness instead of quarter wave.
