Several methods can be used to calculate the radiation emitted, based on various approaches such as geometrical, spectral, statistical, as well as computational simulations. This article presents the computation of net emission coefficients (NECs) for thermal plasma mixtures of H₂O–air–Cu and H₂O–air–Ni. The calculations were performed for isothermal, spherical, and homogeneous plasmas, under the assumption of local thermodynamic equilibrium (LTE), at pressures up to 10 atm and over a temperature range of 300–30000 K. The NEC was obtained by summing the various contributions from atomic continua, molecular continua, atomic lines, and molecular bands. The results emphasize the impact of three parameters on the NECs: temperature, pressure, and plasma thickness. They also demonstrate the crucial importance of metallic vapors on low-temperature plasma radiation owing to the low ionization energy of neutral Cu and Ni compared to the neutral species O, H, and N present in H₂O and air. The values of NEC allow for the estimation of radiative losses in the hot zones of the plasma, in numerical modeling, especially devoted to laser-induced breakdown spectroscopy (LIBS) applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1618-1629"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144623895","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}

Cross-linked polystyrene (XLPS) is always used to manufacture typical insulators for power pulsed generators, so it is important to study the surface insulation performance of the XLPS in a vacuum to improve the normal operation performance of the device. Based on the vacuum surface flashover test platform consisting of a solid-state gigawatt-level pulse generator and a test cavity, XLPS samples with a thickness of 13 mm were used to investigate the influence of roughness on the surface flashover characteristics. Samples with roughness of 1.3, 1.7, 2.2, and <inline-formula> <tex-math>$2.7~mu $ </tex-math></inline-formula>m were tested under both single and 10 Hz modes. It is found that the surface insulation performance of samples increases first and then decreases with the increase of roughness under both modes. Scanning electron microscope (SEM) was used to observe the micromorphology of the sample surface before and after the surface flashover events, enabling analysis of the effect of micromorphology on electron motion. Comparative analysis of the experimental results reveals that the first vacuum surface flashover voltage under both modes primarily depends on the surface roughness. Meanwhile, under 10 Hz mode, the first 50% flashover voltage, the conditioned flashover voltage, and the hold-on voltage are higher than those obtained in single mode, which indicates that the loading condition of the repetition rate pulse has a good aging effect on the sample.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1790-1798"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624027","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}

{"title":"Design and Development of a Line-Type Pulsed Modulator Driver for S-Magnetron for Microwave–Plasma Interaction Experiments in SYMPLE","authors":"Priyavandana J. Rathod;V. P. Anitha","doi":"10.1109/TPS.2025.3575896","DOIUrl":"https://doi.org/10.1109/TPS.2025.3575896","url":null,"abstract":"System for microwave–plasma experiments (SYMPLEs) is an experimental system setup in our laboratory for investigating the interaction of high-power microwave (HPM) with overdense plasma with plasma frequency <inline-formula> <tex-math>$f_{mathrm { pe}} gt f_{mu }$ </tex-math></inline-formula>, the wave frequency. The washer-gun plasma chosen for these experiments is pulsed (<inline-formula> <tex-math>$100~mu $ </tex-math></inline-formula>s) and is operated in single-shot mode. The experimental campaign involves the excitation and launching of a pulsed (<inline-formula> <tex-math>$5~mu $ </tex-math></inline-formula>s) microwave output from an S-Magnetron to the plasma at a predecided temporal regime where the plasma parameters satisfy the required critical requisites for the wave plasma interaction. Therefore it is necessary that the magnetron source is operated in single-shot mode, and the HPM output of all such shots is highly repetitive. The pulsed power driver for the magnetron should thus be capable of giving out highly reproducible (within ±5%) single-shot trapezoidal pulses of maximum 52 kV and 120 A current, with <inline-formula> <tex-math>$5~mu text {s}$ </tex-math></inline-formula> flat top and about 5%–10% rise time, consistent with the requirement of the magnetron. As conventional solid-state modulators pose challenges in achieving shot-to-shot repeatability in single-shot operation, a pulse-forming network (PFN)-based modulator has been chosen despite the stringent pulse rise time requirements. A Guillemin Type-E line-type pulsed modulator has been designed, simulated, and developed indigenously in our laboratory. The design consideration includes the incorporation of a pulse transformer at the output of the pulsed modulator, with the magnetron load impedance of <inline-formula> <tex-math>$433.33~Omega $ </tex-math></inline-formula> constituting the secondary impedance. The primary impedance of <inline-formula> <tex-math>$25~Omega $ </tex-math></inline-formula> is treated as the load impedance for the pulsed modulator. The design approach has involved theoretical estimation of the per-section capacitance, inductance, and coupling coefficient values followed by simulation to determine the best suitable parameters for the 10-stage PFN. A setup consisting mainly of a high-voltage dc charging unit, the 10-stage PFN, a thyratron switch with an appropriate trigger module, and a pulse transformer withbifilar secondary windings has been developed and tested with dummy loads. Experimental results on dummy loads up to 35 kV output give highly reproducible (within ±5%) voltage and current pulses of <inline-formula> <tex-math>$5~mu text {s}$ </tex-math></inline-formula> flat top and about 300–500 ns rise time.

This study investigates the impact of various spoof plasmon topologies T-slot, grating, and L-slot on the miniaturization and performance of THz metamaterial absorbers (MAs). The proposed designs utilize dual-ring and single-ring gold structures on a quartz spacer. Our structures demonstrate up to 15% size reduction while maintaining high absorption rates (96%–98%). The L-slot topology exhibits optimal performance with absorption peaks at 0.758 and 0.984 THz (dual ring) and 1.00 THz (single ring), compared to the conventional design’s 0.77-/1.15- and 1.14-THz resonances, respectively. Comprehensive analyses reveal that spoof structures significantly alter phase response, modify group delay characteristics, and enhance electric field distribution uniformity across the resonator surface. The coupled mode theory (CMT) model accurately predicts these behaviors with parameters extracted from simulation results.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1652-1659"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624053","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 discussion of the application of higher order mode concept to short-pulse time-domain systems is given, which highlights the methodological difficulties associated with such a type of study. A method of dynamical mode analysis in time domain is proposed based on energy considerations and coordinate components of electromagnetic field. Numerical simulations are conducted to study the formation and propagation of modes in a coaxial line partially filled with ferrite, evaluating the influence of nonaxisymmetric modes, axisymmetric TE modes, and axisymmetric TM modes on pulse formation. Such an approach allows to factually demonstrate that the influence of higher order modes on pulse formation in MCLs is negligible, and the main process governing pulse formation is the interaction of nonlinear ferrite material with the fundamental dispersive mode TM₀₀. The presented information deepens the understanding of physical processes occurring in coaxial lines partially filled with ferrite under the application of high-power pulses.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 7","pages":"1531-1542"},"PeriodicalIF":1.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624036","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}
