Abstract
The tunneling time and lateral shift of photon tunneling in a frustrated-total-internal-reflection structure composed of single negative material is derived by employing stationary-phase approximation. It is found that the tunneling time and the lateral shift are negative when the barrier is a single negative material. On account of the Hartman effect of the tunneling time and the lateral shift, the photon tunneling shows the superluminal property. An effective approach to distinguish ε-negative material and μ-negative material is proposed based on the fact that TE- and TM-polarized incident beams experience opposite lateral shift.
