“…2 (a) that the numerically calculated transmission of this structure is almost zero. We think this is caused by the thickness of the gold plane layer in the structure being greater than the thickness of the gold layer in near-infrared [38]. To prove the role and necessity of the gold layer, we also calculate the three spectra of the structure without the gold layer, as shown in Fig.…”

In recent years, multi-band perfect absorbers have great advantages in spectroscopy, infrared detection and other fields. Here we propose and use the finite-difference time-domain (FDTD) method to numerically calculate the multi-band absorber based on 1D gold grating Fabry-Perot (FP) structure. The full-wave simulation results show that under normal incident conditions, four different absorption peaks can be obtained in the near-infrared band and the absorption is all close to 1. These resonance peaks are derived from the third-, fourth-, fifth-, and sixth-order resonances of mode coupling in the FP cavity, respectively. The narrowest absorption bandwidth is 24 nm and the quality factor is 37.6. By adjusting the structural parameters of the grating, its spectrum can be adjusted and selected, and its working angle tolerance can reach 50 •. In addition, numerical results show that the absorber can detect slight changes in the environment when used as a sensor. Therefore, our absorber has potential applications in the field of sensor detection.

“…Ten years later, in 2020, Zhong et al [ 185 ] proposed a NIR multi-narrowband absorber numerically that could target Telecom wavelengths, by adjusting the period, thickness, radius and height of each pillar. Their work suggests Q-factors between 32 and 40, absorption coefficients between 83% and 87% at telecom wavelengths.…”

Surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR) are among the most common and powerful label-free refractive index-based biosensing techniques available nowadays. Focusing on LSPR sensors, their performance is highly dependent on the size, shape, and nature of the nanomaterial employed. Indeed, the tailoring of those parameters allows the development of LSPR sensors with a tunable wavelength range between the ultra-violet (UV) and near infra-red (NIR). Furthermore, dealing with LSPR along optical fiber technology, with their low attenuation coefficients at NIR, allow for the possibility to create ultra-sensitive and long-range sensing networks to be deployed in a variety of both biological and chemical sensors. This work provides a detailed review of the key science underpinning such systems as well as recent progress in the development of several LSPR-based biosensors in the NIR wavelengths, including an overview of the LSPR phenomena along recent developments in the field of nanomaterials and nanostructure development towards NIR sensing. The review ends with a consideration of key advances in terms of nanostructure characteristics for LSPR sensing and prospects for future research and advances in this field.

The emergence of planar metamaterials (PrMMs) has opened a gateway to unprecedented electromagnetic (EM) properties and functionality unattainable from naturally occurring materials, thus enabling a family of PrMM based devices. In this paper, a novel class of superconducting (SC) PrMM is presented and a series of THz reflectance spectral responses simulations reveals that these SC PrMM structures portend applications in a variety of temperature sensors, thermo-optical modulators, and magnetic switch devices.
