Magneto-Optic Effect-Based Metamaterials and Photonic Crystals

About this Research Topic

A magneto-optic effect is any phenomena in which an electromagnetic wave propagates through a medium that has been altered by the presence of a static bias magnetic field. The medium is called gyrotropic or gyromagnetic, in which left- and right-rotating polarizations and elliptically polarized waves can propagate at different speeds, leading to important effects such as Faraday rotation, resonance absorption, birefringence, spin-wave, tensor permeability, or permittivity. Gyrotropic material breaks time-reversal symmetry locally and Lorentz reciprocity, which can cause the nonreciprocity of wave propagation in the material or on the interface of the material. The magneto-optical effects-based metamaterials and photonic crystals widen the scope of gyromagnetic material, which also show some interesting new phenomena.

Magneto-optic effect-based metamaterial and photonic crystals have gained a significant increase in interest recently. The interests include the fabrication of double metamaterials, the enhancement of magneto-optic effects, and the nonreciprocal wave propagation in the metamaterials and photonic crystals. One special interest is the robust chiral edge states or corner states due to the topological phases of photonic crystals. These effects can be achieved by the meta-atom configuration, the coupling among the meta-atoms, and the designs. Exploring the application of the magneto-optic effects and nonreciprocal effects is one of the main interests of the topic.

The aim of the current Research Topic is to cover promising, recent, and novel research trends in the metamaterials and photonic crystals fields including gyromagnetic materials. Areas to be covered in this Research Topic may include, but are not limited to:

· Metamaterials and photonic crystals by gyromagnetic medium

· Enhancement of magneto-optical effect by metamaterials and photonic crystals

· Nonreciprocity of metamaterials and photonic crystals

· Applications of magneto-optical effects and nonreciprocity of metamaterials and photonic crystals


Keywords: magneto-optic effect, gyromagnetic, magnetic metamaterials, magnetic photonic crystals, topological states, nonreciprocal effects, applications of nonreciprocal effects
