In order to detect the magnetic field and temperature effectively, the two sensing channels of the proposed sensor are embedded with gold nanowires and filled with Polydimethylsiloxane (PDMS) and magnetic fluid (MF), respectively. Additionally, this configuration simplifies the fabrication process and eliminates some problems when plasmonic material is deposited in the inner or outer surface of PCF. The performance of the proposed sensor is numerically investigated by the finite element method (FEM). The optimal structural parameters have been determined by analyzing the loss curves and energy of the y-polarized core mode ultimately. Furthermore, the sensitivity is not particularly sensitive to the sizes of the cladding air holes, indicating the sensor has better manufacturing tolerance. The simulation results reveal the maximum magnetic field sensitivity is 238.4 pm/Oe at the magnetic field of 30–300 Oe, and temperature sensitivity is − 1103.6 pm/°C at the temperature of − 20–40 °C. The proposed sensor can detect sub-zero temperatures with a high magnetic field sensitivity. Given its low fabrication complexity and extensive detection range, this PCF-SPR sensor has potential applications in magnetic environments at low temperatures, such as geological exploration, marine environment monitoring, and so on.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213512","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}

It possesses unique properties such as enhancing the strength of the electromagnetic field at the metal surface, achieving sub-wavelength focusing of light waves, and exhibiting low loss. Due to these characteristics, SPP holds great promise in various applications including super-resolution imaging, terahertz technology, biosensing, and optical communication. This paper proposes two Spoof SPP-based tri-band bandpass filters that replace the conventional sawtooth cell structure with a miniaturized labyrinth resonator structure. Upon investigating the dispersion characteristics of the resonators, we found that both resonator unit 1 and resonator unit 2 exhibit three modes, resulting in three notch points for each filter. Unlike most SPP-based structures, our design features a compact structure fed by a co-planar waveguide (CPW) without an added ground at the bottom, thereby reducing losses and improving efficiency. To achieve a smoother transition from CPW to the transmission structure, we utilize a segment of microstrip line structure synthesized by a logarithmic function. Both filters are of the same size, with dimensions totaling 192 mm × 42 mm. Based on our study, we have designed two filters with multiple notch points and have obtained good agreement between the simulation results and the actual test results.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213479","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}

A complete study of power conversion enhancement, in a proposed ultrathin STPV cell, is presented here. It involves lead sulfide colloidal quantum dots (PbS-CQDs), a silver (Ag)-nano-pyramid design, aluminum nitride (AlN) crossed prisms as front texturization, with embedded Ag nanospheres, and a tantalum (Ta) film as a back reflector. By combining the three mechanisms of surface plasmon polariton (SPP), localized plasmons (LSPR), and magnetic polariton (MP) in the same structure, photon absorptance in the active PbS-CQDs layer is greatly improved. The suggested structure attained a highly active absorptance of over 80%, covering visible and near-infrared (0.30–1.77 µm). The short circuit current density is also evaluated under AM 1.5 solar illumination and various blackbody temperatures (TB), with values of 48.90 mA cm−2 and 6.93 mA cm−2, respectively, corresponding to unprecedented power conversion efficiencies (PCEs) of 20.20% and 15.58%. The effects of metamaterial light management on PCE enhancement are discussed. Collectively, the findings show that the proposed hybrid cell is potentially useful in high-performance hybrid thermal and solar cells.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213478","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 sensor design is modelled in two dimensions (2D) and exhibits a broad refractive index detection range, from 1 to 2.5 µm/RIU. The proposed design utilizes a top-analyte configuration, where the target analyte is placed directly on the sensor surface for interaction. Various metals like Ag (silver), Au (gold), Al (aluminium), and Cu (copper) are considered for investigation of the influence of the middle metal layer on the overall optical response. The GST layer is modelled as a two-state material, accounting for its amorphous (aGST) and crystalline (cGST) phases. It allows for exploring the sensor’s tunability based on the GST material’s phase state. Furthermore, comprehensive optimization and validation processes are conducted for various device parameters, including layer thicknesses, widths, and the type of metal employed. These optimizations aim to achieve optimal sensor performance regarding sensitivity and overall functionality. Notably, the simulations reveal distinct bandwidths and resonant regions for both aGST and cGST phases of the GST layer. In conclusion, this proposed sensor provides potential application in biomolecular and chemical testing due to its tunable characteristics and broad refractive index detection range.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935858","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}

Among SPR sensors, D-shaped structures based on photonic crystal fibers (PCFs) have shown very high performance and are easy to use. In this paper, a simple design of SPR sensors based on the D-shaped PCFs with the optimized geometrical parameters is proposed. Gold and silver are considered as plasmonic layers on the surface of the D-shaped PCF sensor. By performing multiple simulations using the finite-difference eigenmode (FDE) method, various values of gold and silver thicknesses are investigated to achieve the highest sensitivity and resolution. The results indicate that the highest sensitivity and resolution of 25,600 nm/RIU and (3.9times {10}^{-6}) are achieved respectively for a gold thickness of 44 nm at the analyte refractive index (RI) of 1.41. Meanwhile, for an analyte RI range of 1.29 to 1.40, silver demonstrates greater sensitivity than gold in the same range.
