Abstract It is theoretically proven that the transmitted Goos--Hänchen (GH) displacement in the symmetry-double prism could be resonantly enhanced when the incident angle is less than but near the critical angle, and is modulated by the slab thickness between two prisms and the incident angle. This enhancement effect is directly observed in microwave experiments in which the incident angle is properly chosen. The measured data are in good agreement with the result of the numerical simulation.
