“…According to this current study on SPR, the comparison of wavelength sensitivity and figure of merit are shown in Table 2. Two different structures obtained a higher sensitivity of 330 μm/RIU [49] and 400 μm/RIU [50], respectively. The former sensor structure was based on metamaterials and obtains a better sensitivity.…”

In this paper, a theoretical model of a surface plasmon resonance (SPR) biosensor based on the insulator-metal-insulator (IMI) structure is proposed. The sensor mainly consists of two IMI structures, MgF2/Au/Al2O3 and Al2O3/Au/sensing medium structure, respectively. Benefits from the symmetrical modes stimulated by the IMI structure, i.e., the electric field strength inside the sensing medium, are reinforced, resulting in a better overall performance in sensitivity and figure of merit (FOM). The influences of the thickness of the metal layers, the parameters of the dielectric layer materials, and the number of structural layers on the performance of this sensor are discussed. When the refractive index (RI) of the analyte varies in the range of 1.3494–1.3495, the optimized sensor could achieve a maximum wavelength sensitivity of 220 μm/RIU (refractive index unit) and a FOM of 3013.70 RIU−1. Compared with the conventional SPR sensor, the sensitivity and FOM of this structure are significantly improved.

“…Furthermore, an increasing number of studies have focused on the combination of HMMs with surface plasmon resonance (SPR) [19][20][21]. SPR is a phenomenon that occurs when a transverse magnetic light wave strikes a metal-dielectric interface, causing longitudinal oscillations in the density of free electrons and leading to a resonant energy transfer from propagating light to surface plasmon polaritons along the interface [22,23].…”

We investigate the Goos-Hänchen (GH) shift in a hyperbolic metamaterial (GHMM) comprising graphene and vanadium dioxide (VO2) as the dielectric. Our study reveals that the dispersion type of GHMM can be controlled via Fermi energy of graphene and temperature, modulating wavelength intervals. Notably, the GH shift in type I dispersion surpasses that in elliptical and type II dispersions. This suggests GH shift control by altering dispersion in GHMM. Thickness variations in VO2 and the number of graphene/VO2 layers minimally affect GH shift. In contrast, graphene thickness significantly impacts GH shift, with thicker graphene yielding minor shifts. Meanwhile, we discover that substantial GH shift enhancement by surface plasmon resonance (SPR) excitation, with sensitivity to refractive index changes in the sensing layer. Based on the above conclusions, we theoretically propose a highly tunable biosensor uniting GHMM with SPR and use it to distinguish normal cells from cancer cells. This work advances optical biosensors and precise physical quantity measurements.

“…[29] A highly sensitive short-range mode resonance sensor made of multilayer structured hyperbolic MMs with a maximum sensitivity of 330 µm/RIU in the near-infrared band has recently been designed. [30] Reference [31] describes a graphene-MoS 2 heterostructure-coated Au GH shift sensor with a sensitivity of 5.545 × 10 5 λ 0 /RIU. The sensibility of a bimetallic sensor based on graphene-hBN heterostructure can be improved by enhancing the GH shift in the infrared band, and a sensibility of 202 × 10 5 λ 0 /RIU can be achieved.…”

We conduct a theoretical analysis of the massive and tunable Goos-Hänchen (GH) shift on a polar crystal covered with periodical black phosphorus (BP)-patches in the THz range. The surface plasmon phonon polaritons (SPPPs), which are coupled by the surface phonon polaritons (SPhPs) and surface plasmon polaritons (SPPs), can greatly increase GH shifts. Based on the in-plane anisotropy of BP, two typical metasurfaces models are designed and investigated. The enormous GH shift about -7565.58 λ0 is achieved by adjusting the physical parameters of BP-patches. In the designed metasurface structure, the maximum sensitivity accompanying large GH shifts can reach about 6.43 × 108 λ 0/RIU, which is extremely sensitive to the size, carrier density, and layer number of BP. Compared with a traditional surface plasmon resonance sensor, the sensitivity is increased at least two orders of magnitude. We believe that investigating metasurface-based SPPPs sensors could lead to high-sensitivity biochemical detection applications.
