The Transverse Magneto-optical Kerr Effect through the Coupling of ε-near Zero and Surface Plasmon Polariton Modes

Structures with near-zero parameters (i.e., media with near-zero relative permittivity and/or relative permeability, and thus a near-zero refractive index) have attracted a lot of attentions. The concept of giant enhancement of the transverse magneto-optical Kerr effect (TMOKE) is demonstrated with amplitudes reaching the maximum theoretical value of +1. The strong electromagnetic field localization in -near zero can excite surface plasmon resonances with no need of a prism or grating. Thus, the magneto-optical devices with opening routes can be miniature and can be used for sensing.
