“…It provides a surface plasmonic platform for efficiently enhancing and manipulating the spin splitting shift [11,18,25,30]. For example, by considering the SPR effect in a metalbased optical structure, the photonic SHE was modulated by adjusting the thickness of the magneto-optical layer and bimetal film [31], and a highly sensitive plasmonic sensor based on photonic SHE was proposed for detection of the biomolecules [32]. Compared to the SPP in metal materials, the graphene surface polaritons have great advantages in the enhancement and manipulation of the photonic SHE due to the tunability by gating or doping, wide operating bandwidth and low losses [28,33].…”

The asymmetric photonic spin Hall effect induced by surface plasmon polaritons in a graphene-based structure is actively manipulated by external magnetic field and electric field. It is revealed that the spin-dependent splitting exhibits spatio-temporal asymmetric property due to the involvement of the anisotropic graphene. The peak of asymmetry degree in asymmetric photonic spin Hall effect at the position of reflectance valley corresponds towards a smaller incident angle with the increase of magnetic field intensity or Fermi energy, which is attributed to the tunability of reflectance for the graphene-based structure. Based on the asymmetric splitting shift, a potential application is proposed for detecting low concentration gas molecules and the detection resolution can be dynamically tunable by changing the magnetic field intensity and Fermi energy. This study may provide a new reference in the fabrication of graphene-based plasmonic sensor devices.

“…Nano-optics is an interdisciplinary subject of nanotechnology and optics. In recent years, by constantly designing structures with different sub-wavelength sizes in order to achieve special interactions with incident light, scientists have succeeded in manipulating certain transmission characteristics of light [1][2][3]. Since metamaterials were proposed, they have attracted the attention of many scholars in this field, and concurrently their related theoretical study [4,5], process [6,7], and applied [8] research are all advancing at the same speed.…”

The introduction of "metamaterials" has had a profound impact on several fields, including electromagnetics. Designing a metamaterial's structure on demand, however, is still an extremely time-consuming process. As an efficient machine learning method, deep learning has been widely used for data classification and regression in recent years and in fact shown good generalization performance. We have built a deep neural network for ondemand design. With the required reflectance as input, the parameters of the structure are automatically calculated and then output to achieve the purpose of designing on demand. Our network has achieved low mean square errors (MSE), with MSE of 0.005 on both the training and test sets. The results indicate that using deep learning to train the data, the trained model can more accurately guide the design of the structure, thereby speeding up the design process. Compared with the traditional design process, using deep learning to guide the design of metamaterials can achieve faster, more accurate, and more convenient purposes.
