Using Yasumoto and Õishi’s energy flux method, a generalized analytical formulation for analyzing the Goos–Hänchen (GH) shift in frustrated total internal reflection is provided, from which the GH shift given by Artman’s stationary phase method is shown to equal the GH calculated by Renard’s conventional energy flux method plus a self-interference shift. The self-interference shift, originating from the interference between the incident and reflected beams, sheds light on the asymptotic behavior of the GH shift in such optical tunneling process in term of energy flux.
