Despite advances in techniques such as analytical models and computational simulations, challenges remain due to differences in experimental parameters that limit their real-world applicability. Digital photoelasticity offers promise in stress analysis, particularly through isochromatic fringes, but faces hurdles in quantifying stress information from dynamic color changes. To address this gap, this paper proposes a novel approach based on pattern recognition within a single polariscope configuration. By analyzing color trajectories of pixel positions individually, the approach aims to overcome spatial dependencies and improve the accuracy of stress field evaluation. Potential results include a better understanding of dynamic stress behavior and more accurate identification of stress patterns, contributing to improved engineering designs and structural reliability.

The filter operates based on Surface Plasmon Polaritons (SPPs), which are excited at the metal-dielectric interface, allowing for a compact design with excellent optical performance. The filter design was optimized through a combination of numerical simulations using the Finite Difference Time Domain (FDTD) method and theoretical analysis. The simulation results indicate that the filter achieves a high-quality factor of 272 at a resonance wavelength of 818 nm and a cavity width (d) of 35 nm, significantly outperforming previously designed filters. Additionally, the paper presents a detailed comparison of the plasmonic performance of silver and gold, examining their effects on the quality factor, transmission spectrum, resonance wavelength, and overall optical performance. The results highlight that the choice of material plays a crucial role in optimizing the filter’s characteristics, as silver demonstrates a higher-quality factor and sharper resonance compared to gold. The filter's high-quality factor provides excellent wavelength selectivity and suppresses unwanted interference effectively, ensuring efficient performance. Moreover, the proposed structure exhibits a small full width at half maximum (FWHM) and tunable resonance wavelengths through precise control of geometric parameters such as cavity dimensions and resonator shape. These tunable characteristics make the filter highly suitable for advanced photonic applications, including optical filtering, high-speed communication systems, and biosensing. The significant results of this study confirm that the proposed plasmonic filter structure is a promising candidate for future nanophotonic systems, where high efficiency and precise wavelength control are essential.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"334 ","pages":"Article 172401"},"PeriodicalIF":3.1,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144116876","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}

By toggling these switches ON and OFF, the antenna operates in nine different modes. A single-layer metasurface reflector (MSR) was integrated below the FRSA to enhance the antenna's gain and directivity.
