Terahertz metamaterial absorbers (TMAs) can efficiently absorb electromagnetic wave in the range of 0.1–10 THz based on the tunable electromagnetic properties of artificially designed unit cells. TMAs can achieve perfect absorption, as well as broad band absorption. Specifically, TMAs can break the thickness limit of a device at a quarter wavelength, realizing ultra‐thin devices so as to facilitate integration with other systems. Accordingly, TMAs have high application value in communication, imaging, detection, security inspection, and other fields because of their characteristics of small size, perfect absorption, less restriction of natural materials, and tunable electromagnetic parameters. This review covers the fundamental principles and recent advances of TMAs, from the essential structural features of TMAs and working principle of various types of TMAs to the design and applications of corresponding structures, especially the TMAs that can be tuned by various approaches. The development trend and challenges of TMAs are briefly discussed too. It is envisioned that this review can help R&D of the future TMAs for real applications.

“…Cheng et al conducted experiments to investigate the effect of substrate surface roughness on the growth rate and microstructure evolution of intermetallic compound layer with Ni-W-P coating. The results show that the increase of the surface roughness of the substrate will increase the surface roughness of the coating and affect the phase transformation of the microstructure of the coating to a certain extent [15]. Tian et al studied the corrosion resistance mechanism of Ni-W-P coatings on AZ91D magnesium alloy.…”

The corrosion of materials in sea environment are generally caused by salt spray, tidal action and adhesion of marine organisms. It is necessary to ensure the materials possess the required strength and good corrosion resistance during operation. Although the existing Ni-W-P electroless plating can provide a certain degree of corrosion protection, its corrosion resistance is still limited under harsh marine condition. SiO2 nanoparticles have received extensive concern due to their excellent corrosion resistance, which has been considered as potential candidates for enhancing corrosion resistance in multicomponent electroless coatings. In this study, the electroless Ni-W-P coatings with SiO2 nanoparticles co-deposition on the Q235 substrate was prepared. The coating was characterized through scanning electron microscopy (SEM), X-ray diffraction (XRD), polarization techniques, and electrochemical impedance spectroscopy (EIS). As a result, the Ni-W-P coating co-deposited with SiO2 nanoparticles demonstrates superior corrosion resistance compared to the pure Ni-W-P coating. The surface of SiO2 nanoparticles contain three distinct bonded hydroxyl functional groups, which can influence the ionic reaction in the plating solution and the deposition of elements in the coating. After modified by PVA, it can be uniformly dispersed in the coating, and the composite coating with SiO2 nanoparticles co-deposited is transformed into a nanocrystalline structure. The even distribution of SiO2 nanoparticles fill the defects within the coating, leading to a reduction in porosity, permeability, and susceptibility to penetration of corrosive media. Concurrently, the nanoparticles facilitate surface passivation, forming a stable interface with substrate and coating that inhibits electrochemical reactions and diminishes the rate of self-corrosion reactions. The good and stable corrosion resistance is achieved at the SiO2 concentration of 9 g/L and PVA concentration of 1.08 g/L. These findings offer valuable insights for addressing corrosion challenges in the field of marine engineering.
