If the medium #2 is a PEC, i.e. η₂ = 0, ε_r2 = ∞, the reflection coefficient is . The total field components, in the medium #1, are given below from equation (5.2.9); while in the medium #2 there is no field:

(5.2.11)

In equation (5.2.11a, b, c) harmonic‐time dependence e^jωt is suppressed. It is seen from equations (5.2.11a, b, c) that the interference produces a total wavefield moving in the y‐direction along the interface, while along the direction of the normal, i.e. in the x‐direction, it is a standing wave. It shows that the interference field pattern is traveling along the interface.
