The numerical investigation focuses on the impact of varying nanorod radius on the sensor’s performance. Results show that two distinct resonant dips in the transmittance spectrum are identified in the near-infrared region, where the second dip has found to have a heightened sensitivity which is particularly advantageous for chemical and biological sensing. The study reveals that increasing the nanorod radius enhances sensor sensitivity and results in a noticeable red shift in dip positions. The sensor attains a peak sensitivity of 2105 nm/RIU at nanorod radius of 22 nm. Furthermore, the proposed sensor is examined for its effectiveness in detecting adulteration in pure honey by sensing the change in resonance wavelength. The observations reveal the sensor’s capability to identify the percentage of externally introduced glucose and fructose in the honey by indicating shifts in resonance wavelength.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"1 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The structure is composed of a metal-insulator-metal (MIM) S-shaped waveguide with baffle, an analogous C-shaped resonator (ACR), and a T-shaped resonator with an annular cavity (TRAC). Employing the finite element method (FEM), the optical transmission characteristics of the structure are investigated. The results indicate that the dual Fano resonances arise from different resonators and can be independently tuned by altering the structural parameters of different resonators. Then, through adjusting the refractive index (RI) of the medium within the resonator in the range of 1.3–1.4, the RI sensing properties of the structure are also analyzed. The maximum RI sensitivity (S) and figure of merit (FOM) can be up to 2400 nm/RIU and 95.86 RIU−1. Moreover, depending on the independence of the ACR and the TRAC, the sensor has efficient biochemical sensing characteristics and is used to achieve simultaneous determination of water-soluble vitamin B1 and vitamin C. The corresponding concentration sensitivities can be up to 500 nm·ml/g and 224 nm/Cvc, respectively. Consequently, the structure has significant potential for multifunctional biochemical sensing applications in high-density integrated circuits.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"171 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

However, noble metals provide less tunability to control the electromagnetic (EM) surface wave. Therefore, it is imperative to design dynamically tunable plasmonic devices. In this manuscript, a theoretical model is developed for a graphene-filled waveguide surrounded by uniaxial chiral material (UACM). The complex conductivity of graphene is modeled with the help of the eminent Kubo formula. By applying boundary conditions at the interface, the characteristic equation is derived to investigate the behavior of the normalized propagation constant for the proposed waveguide. The variation in normalized propagation constant under the different parameters of graphene such as chemical potential, relaxation time, number of layers as well as values of chirality for different cases of UACM, i.e., ({varepsilon }_{text{t}}) > 0, ({varepsilon }_{text{z}})> 0, ({varepsilon }_{text{t}}) < 0, ({varepsilon }_{text{z}}) < 0 and ({varepsilon }_{text{t}}) < 0, ({varepsilon }_{text{z}}>) 0 is analyzed in the THz frequency range. This study reveals that the normalized propagation constant is very sensitive when both longitudinal and transverse components of permittivity exhibit a negative sign (({varepsilon }_{text{t}}) < 0, ({varepsilon }_{text{z}}) < 0) as compared to the other two cases. It is observed that all three types of UACM have different cutoff frequency ranges. Field profile of UACM such as ({E}_{text{z}}) and ({H}_{text{z}}) also studied to confirm the existence of SPP. The present work holds promising potential to offer a new platform graphene-UACM-based plasmonic devices that can be utilized to fabricate waveguides that are dynamically tunable in different THz frequency regions.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"77 4 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In the developing design construction, the three appropriate layers have been composed to perform a good solar absorber with different types of materials such as zirconium (Zr) as the resonator design, iron (Fe) used as the substrate section, and the ground titanium (Ti). With the help of a thin graphene layer addition, the current solar absorber improved the radiation observed and can able to extract the ultraviolet (UV) area, visible (V) regime, and also middle-infrared (MI) region. With the exact number of wavelengths and bandwidth expression, more than 97% of the rate has been extracted from 0.2 to 1.1 µm for 900-nm bandwidth, higher than 95% is 600-nm bandwidth between 0.1- and 1.7-µm wavelength, and the whole range of 2800-nm band rate is 90.43% respectively. To study the varied absorption rates in accentuation, the best four wavelengths of 0.2, 0.48, 0.81, and 1.21 µm are selected. To present the current work systematically, we divided the several sections into design and parameters, results and discussions, and conclusion. The current graphene-based absorber of Zr-Fe-Ti can be applied in warm builds, water heating systems, space heating, distillation, drying, and so on. Moreover, a large area of industrial heating process and artificial photosynthesis can be used.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"275 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The core innovation of the sensor design lies in the integration of the two-dimensional nanomaterial black phosphorus with a corrugated silver layer. This synergistic combination significantly amplifies the interaction between the analyte and the sensing surface, thereby markedly enhancing the sensor’s performance. The influence of the corrugated silver layer and multi-layer black phosphorus on the sensing performance of the proposed sensor was analyzed using numerical simulations. By optimizing structural parameters, including the number of black phosphorus layers and the thickness and period of the corrugated silver layer, the sensor achieved ultra-high sensitivity and an exceptional figure of merit. Within the refractive index range of 1.330 RIU to 1.335 RIU, the sensor exhibited an average sensitivity of 1630°/RIU and a figure of merit of 217.333/RIU. Compared with previously reported prismatic surface plasmon resonance refractive index sensors, the proposed sensor exhibits significantly enhanced angle sensitivity. This sensor is particularly well-suited for detecting biomolecules, including the SARS-CoV-2 virus. It demonstrates substantial potential for applications in high-precision biomedical detection and medical diagnostics.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"34 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
