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":null,"pages":null},"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":null,"pages":null},"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":null,"pages":null},"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}

The transmittance characteristics of the proposed design are studied using the finite difference time domain methodology.

Since Pd can absorb hydrogen (H(_2)) and converts to Pd-H, its permittivity is completely different from that of Pd-H, so the optical response of the system will be also change. The results of electric field distributions and propagation lengths of seven modes of the designed structure are obtained by calculations. For different modes, it is found that the propagation length increases with the increase of mode order. The propagation lengths of the same mode in the structure of Pd and Pd-H are respectively compared, and it is discovered that it is also different due to the change of dielectric constant before and after H(_2) absorption. The results show that in the double nanowire structure, the propagation lengths of structures with Pd are larger than the ones of structures with Pd-H for each mode. The distance of the two nanowires impacts on the coupling between the two nanowires. By changing the radius of Ag nanowire, the propagation lengths of the fundamental mode increase, while the ones of the harmonic modes decrease. There is an optimal thickness to make the propagation length longest for each mode by changing the thickness of Pd, which shows the competition between the dissipation of the structure and the coupling between SPPs in different layers. The structure we designed can be applied to the direction of the hydrogen sensor to realize the monitoring of its state when using hydrogen energy to ensure safety.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213468","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}
