Using the multilayer homogenization technique, we have found some effective permeability that is automatically neglected in the conventional Drude plasma approximation which only considers permittivity. It can seriously affect the desired impedance matching with free space above the plasma frequency. To improve the impedance matching, and thus reduce ripples above the plasma frequency, it is necessary to design unit cells with high equivalent self-inductance. According to theoretical and numerical results, we have demonstrated that the replacement of straight strips with zigzag strips of the same width can considerably improve the quality of the impedance matching.

Since the hexapole localized surface plasmon resonance (LSPR) mode has equivalent dipole moments in the directions of both X and Y, it has the ability to disperse electromagnetic waves in the plane's X and Y directions, making it possible for the hexapole LSPR to couple with Rayleigh anomalies in two orthogonal directions. This paper proposes a gold nano-hexagonal prism array structure that can excite multiple surface lattice resonances without designing complex polymer structures. Due to the particularity of the regular hexagonal prism structure, the tip effect is introduced to enhance the hexagonal LSPR mode in a targeted manner. The numerical simulation and modal field analysis results show that the hexagonal LSPR of the gold nano-hexagonal prism array structure can couple with two periodic Rayleigh anomalies in the plane, resulting in two surface lattice resonance peaks. The structure can also be excited by incident light to generate an out-of-plane dipole mode, which couples with Rayleigh anomalies to form a surface lattice resonance peak.

To address this challenge, we propose a method to accelerate the near-field data acquisition phase, which is often the most time-consuming. This involves constructing two-dimensional near-field data by symmetrically expanding a one-dimensional metalens in a circular pattern. Our findings show that this approach can achieve a speedup of over 100 times, with potential for even greater efficiency as metalens size increases.

In the ultra-long operating band of 8–36 μm, the average absorption rate is as high as 95.79 %, brought about by the resonance excitation of various modes, including local surface plasmon resonance, guided mode resonance, cavity resonance, magnetic resonance, and diffraction. At a large incidence angle of 60°, the absorption of the absorber can reach 91.17 % in TE mode, demonstrating insensitivity to large-angle incidence. At 1800 K, the absorber shows an emission efficiency as high as 97.01 % in the long-wave infrared range. It is worth mentioning that our absorber exhibits an extremely large manufacturing tolerance of ± 0.4 μm, making it highly suitable for practical production and application. Therefore, the proposed absorber shows promising potential in applications such as infrared imaging, infrared detection, hot electron collection, radiative cooling, and other related fields.
