Abstract

Tunneling of microwave radiation through a symmetrical trilayer ENG-ferrite-ENG is considered, where ENG refers to a medium of negative permittivity. Such trilayer is an example of a magnetically controlled structure that under certain conditions allows a complete (or perfect) tunneling of the incident radiation. In this paper, the general conditions of the perfect tunneling are analyzed, and the transmissive properties of the structure are studied numerically. It is demonstrated that a broad passband, in which the structure is almost completely transparent, may be obtained both above and below the frequency of the ferromagnetic resonance. The bandwidth can be effectively controlled by an external field that is magnetizing the ferrite layer.
