Extraordinary transverse magneto-optical Kerr effect through excitation of bulk plasmon polariton modes in type II magneto-optical hyperbolic metamaterials

In this work, we theoretically demonstrate the giant increment of the transversal magneto-optical Kerr effect in a type II hyperbolic metamaterial composed of four pairs of dielectric/metal layers, where the dielectric material presents magneto-optical activity. The enhancement is a consequence of high localization of the electromagnetic field inside the metamaterial given by excitation of the lowest order-bulk plasmon polariton mode.

Automated summary

This work theoretically demonstrates a significant enhancement of the transversal magneto-optical Kerr effect in a type II hyperbolic metamaterial through excitation of the lowest order-bulk plasmon polariton mode, leading to high localization of the electromagnetic field inside the metamaterial.
