Magnetically Controlled Tunneling of a TE Wave through the Ferrite—ε-Negative Layer Structure

Аннотация

We have considered the tunneling of a normally incident electromagnetic wave through a bilayer structure that consists of a ferrite layer and an adjoining layer with a negative permittivity. The ferrite layer is transversely magnetized by an external magnetic field that corresponds to the range of negative values of the effective permeability. It has been shown that the transmission of the structure can be controlled in wide limits by varying the external magnetic field. In particular, nearly perfect tunneling (viz., nonreflective transmission of incident radiation) can be realized.
