However, single-band functionality of these sensors might lead to false-positive result. In this article, we present an angularly stable (up to ±40°) triple-band microscale MS absorber in THz domain and its utility to unprecedented applications toward multifold sensing. With ultranarrow linewidth and close-to-perfect absorbance, the suggested MS absorber delivers near-perfect triple-band absorption around 1.675, 3.504, and 5.694 THz. The absorption feature is validated by an in-house equivalent circuit model (ECM). Owing to the ultranarrow absorption peaks in the THz domain, the intended metasensor demonstrates high sensitivity and figure of merit (FoM) toward variations in refractive index (RI) of the analyte layer; thereby, finding it capable to detect and distinguish various types of cancers, tumors, viruses, tuberculosis, malaria, hemoglobin content in blood, and glucose content in water.

In order to analyze the expansion characteristics of cathode spots (CSs) on the 126 kV axial magnetic field (AMF) contacts, the drawn vacuum arc experiments were conducted. To observe more characteristics of the drawn vacuum arc, two high-speed cameras were used simultaneously to capture the dynamics of both the vacuum arc and CSs. The experimental results indicated that the vacuum arc column could not expand sufficiently to cover the entire contact surface. Additionally, multiple types of vacuum arc column modes occurred in the experiments, and the number of ignition positions also affected both the appearance of vacuum arc and the diffusion process of CSs. Moreover, the magnetic field distribution under different vacuum arc column modes was simulated. In the contact surface near the contact edge, the AMF components are smaller than the transverse magnetic field (TMF) components and these lead a rapid radial expansion of CSs. Furthermore, significant deflection occurs for CSs located in central area on both cup-type AMF contact and coil-type contacts. However, the CSs of these two types of contacts show different deflection directions. When the total arc area remains constant but the number of arc columns increases, the TMF components decreases and radial velocity of CSs also decrease. The simulation results also indicated that the variation in the number of arc columns has a relatively small impact on the distribution of the AMF component.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1592-1603"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624014","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 generator is designed to meet the portability requirements and generate high-voltage pulses with a short rise time and high repetition rate. To achieve a high step-up ratio efficiently, an inductive isolation-based Marx generator is employed, driven by a high-voltage capacitor charger (HVCC). The HVCC is designed with a Cockcroft-Walton voltage multiplier (CWVM)-based bipolar hybrid symmetrical voltage multiplier (BHSVM) to increase the low battery voltage (24 V) to over 60 kV, ensuring effective high-voltage boosting and insulation. Additionally, an equivalent modeling technique is proposed for the BHSVM circuit, and based on this, an LCC resonant converter was implemented without additional magnetic components. The parameters of the LCC resonant converter were designed to enable soft switching across the entire output voltage range, considering the repeated charging and discharging involved in the application. Moreover, the design incorporates a high-voltage transformer with insulation of >10 kV and a charging cable instead of the conventional charging resistor, ensuring both insulation and charging resistance. Simulations validated the accuracy of the BHSVM equivalent model and the high-efficiency operation of the LCC resonant converter across the full voltage range. Experimental results demonstrated that the compact, high-density high-voltage pulse generator can deliver high-voltage pulse at the repetition rate of 120 Hz to the antenna and UWB EMP with an amplitude of 421 kV and a rise time of 0.5 ns.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1543-1551"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144623960","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}

Compared with conventional nanosecond pulse generators for ns-APPJ, the inductive voltage adder (IVA) is capable of achieving high-voltage step-up ratios through electromagnetic coupling while simultaneously reducing insulation requirements. In this study, a solid-state nanosecond IVA with variable winding is proposed. The apparatus consists of ten stages coupled with nanocrystalline cores, producing 10-kHz repetitive pulses on capacitive loads. The output voltage is up to 24 kV with a step-up ratio of 53.3 and a turn ratio of 1:3 with a load capacitor of 400 pF. The minimum full-width at half-maximum (FWHM) on capacitive loads is 100 ns with a narrow falling edge owing to a designed magnetic switch. The influence of parasitic parameters on pulse performance is analyzed, and pulse specifications and circuit parameters are discussed. Furthermore, the generator is used to drive an argon plasma jet using a coaxial pin-ring electrode. The APPJ is diagnosed by optical emission spectroscopy (OES). This study provides a feasible design for nsPEF-driven plasmas.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1763-1771"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624052","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}
