Abstract
Tunneling of microwave radiation through a symmetric three-layer structure in which the central ferrite layer is interfaced with two layers of a material with negative permittivity is considered. Conditions for perfect tunneling (i.e., transmission with zero reflection) are analyzed for normal incidence. It is shown that the transmittance of the structure can be controlled using external magnetic field that provides magnetization of the ferrite layer. A broad transmission band with a width of several gigahertzes in which almost perfect tunneling is implemented can exist in the frequency range corresponding to the negative effective permeability of the ferrite material.
