Abstract

We theoretically investigate the propagation characteristics of transverse electric (TE) waves in a waveguide consisting of a nonlinear metamaterial and a linear ferromagnet. The investigation shows that the TE waves exist in a form of a surface wave localized at the interface between the metamaterial and ferromagnet and propagate backward in the metamaterial and forward in the ferromagnet. The effective wave power in the waveguide can be well balanced for some incident frequencies. It is manifested that the guiding structure exhibits the properties of passband and stop band that can be adjusted and switched into each other by controlling the intensity-dependent parameter at the interface. It is expected that such wave characteristics could provide ideas for novel device design and potential applications in information processing.
