comment Total internal reflection and waveguides
The phase shift below the critical angle is always $\pi$ because the interface is acting as a mirror, i.e. the reflected electric field is the mirror image of the incident electric field. You can regard this as having the real valued $R$ expressed in terms of its magnitude multiplied by $e^{j 2 \pi} = 1$. When the critical angle is surpassed the interface is no longer acting as a mirror, but as something else, and phase shift occurs. I sometimes use j instead of i as the imaginary unit.
