Goos-Hnchen (GH) shifts of the transmitted and reflected light beam in a two-prism configuration is staturated to a maximum in the opaque limit for the incidence angle above the critical angle for total reflection. The magnitude of GH shift is about the order of the wavelength. The Goos-Hnchen shift of the transmitted light beam in a two-prism configuration is investigated by stationary-phase approach when the incidence angle is less than the critical angle. It is shown that the Goos-Hnchen shift of the transmitted light beam in propagating case is a periodical function of the air-gap thickness, incidence angle and the refractive index of two prisms. Due to transmission resonance, the Goos-Hnchen shift of the transmitted light beam can be of one or two order of wavelength. Compared to the result for the incidence angle above the critical angle, the Goos-Hnchen shift presented here can be resonantly enhanced by boundary interaction effect. It is also shown that the Goos-Hnchen shift of the reflected light beam is the same as that of the transmitted one in the symmetric structure, when the resonance does not occur. These resonance-enhanced shifts of the transmitted light beam may lead to potential applications in the optical devices, such as optical switch and optical coupler.
