With the transfer-matrix method, conditions of extraordinary electromagnetic resonant tunneling through all combinations of three-layer nonmagnetic (µr = 1) media containing epsilon-negative (ENG) and doublepositive (DPS) slabs were explored. We show that abnormal phenomena can occur in the ENG-DPS-ENG structure, without any restriction on the permittivity of the DPS layer. Changes of transmittance as a function of frequency and incidence angle for a dispersive, lossy model are also calculated, and the results demonstrate the possibility of exhibition this counterintuitive tunneling phenomenon in the DPS-ENG-DPS structure within a wide range of incidence angles.
