“…Magnetic materials also provide a platform for realizing nonreciprocal phenomena, resulting from the breaking of time-reversal symmetry due to the existence of the external magnetic field. For example, magnetically controllable nonreciprocal Goos-Hänchen shift has been predicted in plasmonic gradient reflective metasurfaces, [87] whereas ferrites can be used in devices exploiting magnetic surface plasmons to implement tunable unidirectional absorptive metasurfaces, [86] as illustrated in Figure 4c,d.…”

Metasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of attention for their capability to manipulate electromagnetic waves. Recent advances in reconfigurable and programmable metasurfaces have greatly extended their scope and reach into practical applications. Such functional sheet materials can have enormous impact on imaging, communication, and sensing applications, serving as artificial skins that shape electromagnetic fields. Motivated by these opportunities, this progress report provides a review of the recent advances in tunable and reconfigurable metasurfaces, highlighting the current challenges and outlining directions for future research. To better trace the historical evolution of tunable metasurfaces, a classification into globally and locally tunable metasurfaces is first provided along with the different physical addressing mechanisms utilized. Subsequently, coding metasurfaces, a particular class of locally tunable metasurfaces in which each unit cell can acquire discrete response states, is surveyed, since it is naturally suited to programmatic control. Finally, a new research direction of software‐defined metasurfaces is described, which attempts to push metasurfaces toward unprecedented levels of functionality by harnessing the opportunities offered by their software interface as well as their inter‐ and intranetwork connectivity and establish them in real‐world applications.

“…The phenomenon was first experimentally observed by Goos and Hänchen in total internal reflection (Goos and Hänchen, 1947), which is further developed again because of the finding of giant and negative GH shifts (Shadrivov et al, 2003;Wang et al, 2005). In 2019, magnetic plasmonic gradient metasurfaces have been designed, which can be operated as a platform to implement nonreciprocal GH shift (Wu et al, 2019). The GH shift is controlled intrinsically by tuning the rotational gradient, or extrinsically by tuning the bias magnetic field for specified magnetic gradient metasurfaces.…”

The topological state in photonics was first realized based on the magnetic-optic (MO) effect and developed rapidly in recent years. This review summarizes various topological states. First, the conventional topological chiral edge states, which are accomplished in periodic and aperiodic systems based on the MO effect, are introduced. Some typical novel topological states, including valley-dependent edge states, helical edge states, antichiral edge states, and multimode edge states with large Chern numbers in two-dimensional and Weyl points three-dimensional spaces, have been introduced. The manifest point of these topological states is the wide range of applications in wave propagation and manipulation, to name a few, one-way waveguides, isolator, slow light, and nonreciprocal Goos–Hänchen shift. This review can bring comprehensive physical insights into the topological states based on the MO effect and provides reference mechanisms for light one-way transmission and light control.

“…Based on the three-dimension SRR structure, a wealth of intriguing functionalities have been reported in recent years, for example, tunable devices [23], beam steering [24], quantum phenomenon-like response [25], [26], high-quality toroidal resonance excitation [27], plasmon coupling [28] and sensors [29]- [31]. Beyond that, magnetic metamaterials which have stimulated a wide varieties of applications of significant importance including magnetically controllable physics [32]- [34], nonlinear effect [35], magnetoelastic metamaterials [36], optical activity [37], magnetic surface plasmon [38], [39], nonreciprocal waveguiding [40] and absorption [41] and medical imaging [42], are as useful as the electric counterpart and worth in-depth study.…”

Magnetic resonators based on metamaterials are valuable for numerous applications including perfect absorber, sensing and medical imaging. However, due to the existence of the difficulty in magnetic excitation in planar metasurface, the study of magnetic metamaterial resonators is less reported, particularly in contrast to the electrical resonators. In this paper, the three-dimensional split ring resonator (SRR) metamaterials featuring dualband magnetic plasmonic resonance modes are proposed and numerically analyzed. We calculate the electromagnetic field distributions of the three-dimensional metamaterials at the resonant frequencies to elucidate the resonant characteristics of the dual modes (fundamental LC mode and high-order magnetic plasmonic resonance mode). The influences of geometric parameters of the constituent meta-atoms on the resonance frequencies of the two resonance modes are analyzed by numerical calculations. The results show that the resonance frequency of the high-order magnetic resonance mode is nearly independent of the standing columns of the metamaterials owing to the special resonant characteristic of the high-order mode. Benefiting from the independence, the frequency interval between the dual modes can be customized by adjusting the dimensions of the column. In addition, by tuning the dimension of the columns, the quality factors of the resonances can reach the highest value of 176 for LC mode and 270 for the high-order mode, respectively. In light of practical application, we evaluate refractive index sensing performance of the proposed metamaterials, the maximum sensitivity can reach 474 GHz/RIU for LC mode and 446 GHz/RIU for high-order resonance, respectively. We also explore the universality of the special resonant characteristic of the high-order mode in other similar three-dimension SRR metamaterials, which shows all of these three-dimension magnetic plasmonic metamaterials provide potential platforms for multiband magnetic metamaterial applications.
