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. This work provides new understanding and data support for the design of multiple surface lattice resonance devices by presenting in detail the properties of the structure's three surface lattice resonance peaks varying with structural parameters.</div></div>","PeriodicalId":49699,"journal":{"name":"Photonics and Nanostructures-Fundamentals and Applications","volume":"63 ","pages":"Article 101360"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143167028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Absorption in the long-wave infrared band is an important focus of infrared research and has attracted a great deal of attention from researchers. In this work, a long-wave infrared ultra-wideband absorber based on a four-layer metal–dielectric–metal–dielectric structure is proposed. 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. In addition, the absorber can be used in remote sensing applications, as its operating band effectively covers the common remote sensing band from 8 to 30 μm.</div></div>","PeriodicalId":49699,"journal":{"name":"Photonics and Nanostructures-Fundamentals and Applications","volume":"63 ","pages":"Article 101357"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
