The identification process is based on experimental input/output measurements. The validation of the parameter results is done by a physical analysis of the behaviors of these parameters and by comparing the output calculated according to these parameters, with the real output obtained experimentally. The results show that with a constant forgetting factor close to 1 (<inline-formula> <tex-math>$lambda = 0.99$ </tex-math></inline-formula>), parameter quality improves but output accuracy may vary. In contrast, a variable forgetting factor enhances both parameter quality and model output consistently.

The self-consistent nonlinear theory is composed of the electron motion equation and the electron excitation equation, which could accurately describe the interaction process between the electron beam and electromagnetic wave. The MCG is optimized to generate a large-orbit beam (LOB), and the complex cavity is designed to suppress parasitic modes and improve the output efficiency. The complex cavity gyrotron is optimized to operate at a frequency of 1-THz, achieving an output efficiency of 1% and an output power of 0.5 kW when the beam voltage is 59 kV, the beam current is 0.8 A, and the magnetic field is 9.9 T. The effects of the beam voltage, the beam current, and the pitch factor of the electron beam on the output efficiency are analyzed. Results show that when the beam voltage varies between 57 and 61 kV, the beam current between 0.3 and 1.2 A, and the pitch factor between 1.05 and 1.5, the output efficiency of the gyrotron is maintained above 0.7%.

The electromagnetic (EM) scattering characteristic of a time-varying hypersonic target with a dusty plasma coating in the BGK collision model is studied by calculating the radar scattering cross section (RCS) with varying dust particle radius, dust particle concentration ratio, dusty plasma relaxation time, collision frequency, incident angle, and time-varying laws of electron density in the dusty plasma. Results show that the increase in dust particle radius and concentration, as influenced by the charging effect of dust particles, enhances the scattering of EM waves. This improvement leads to the increment in RCS. The augmented charging and collision frequencies of dusty plasma intensify the collision effect of electrons, ions, and dust particles, which decreases RCS. In addition, the effects of different incident angles and time-varying laws on the RCS are analyzed. In addition, the change in incident angle causes deviations in the overall change in RCS. Furthermore, different time-varying laws change the oscillation amplitude of RCS to some extent. These results provide theoretical support for solving the “communication blackout” problem.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 1","pages":"116-121"},"PeriodicalIF":1.3,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465836","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}

Here, we develop a 2-D unipolar ion discharge model by using electrohydrodynamic (EHD) methods coupled with Navier-Stokes (N-S) equations. The effects of conductor cross-sectional geometry and voltage levels on the distribution of electric field, characteristics of ionic wind, and distribution of EHD force during the corona discharge have been studied. It is shown that both the cross-sectional geometry and voltage level have significant influence on the aerodynamic characteristics of the conductor. A higher corona inception field strength can be produced when the conductor geometry is closer to a cylindrical shape. As the number of strands in the conductor is increased, the cross-sectional geometries become more complex, leading to greater electric field distortion, which assists the ionic wind effect and maximum composite velocity. Higher voltage levels inhibit the ionic wind speed, resulting in a reduced maximum composite velocity. Moreover, the increases in the number of conductor strands and voltage levels can enhance the EHD force, inducing the fluctuations in ionic wind velocity around the conductors. Our results provide insights into ionic wind generation from corona discharges in transmission lines and offer theoretical guidance for mitigating the corona-induced vibrations.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 1","pages":"99-107"},"PeriodicalIF":1.3,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465837","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 coupled electromagnetic-mechanical–thermal physical model was established and validated for characterizing electromagnetically driven shaped liners. The parameters of the liner structure were optimized for high velocity and strong penetration jet. The outcomes demonstrated that the current and magnetic fields concentrated on the outer surface of the liner at the beginning of loading. Subsequently, they gradually diffused in the thickness direction due to magnetic diffusion. The liner was heated and even ablated by joule heat at current density with several mega-amperes per centimeter.

Within the diffusion depth, some material near the apex vaporized, while most of the area remained in a solid or liquid state. The collapse velocity increases with decreasing thickness under the same loading conditions. The current density decreases due to the increase in the diameter, and the overall velocity of the liner with a larger cone angle is smaller than that of a smaller cone angle. The tendency and law of the current density, magnetic diffusion depth, and ablation thickness on the loading surface are similar. Furthermore, the ablation near the apex with a larger cone angle is more severe. A shaped liner with a small cone angle is suitable for obtaining a jet with high velocity and strong penetration.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 12","pages":"5633-5640"},"PeriodicalIF":1.3,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106390","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 formation and propagation of streamers is an inherently stochastic process, which leads to cycle-to-cycle variations in streamer properties. The present work quantifies these variations through electrical measurements of a plasma jet striking a conductive substrate. It was found that streamer ignition and magnitude can change substantially from cycle to cycle and thus differ from time-averaged measurements taken over many cycles. For example, the energy required to drive the plasma jet and the amount of charge delivered to the substrate during a given cycle can vary from their respective averages by a factor of 2 or more. While some of this can be due to power supply stability, several other operating characteristics of the plasma jet were found to influence repeatability. It was found that helium and argon produced plasma jets with different levels of repeatability, with the repeatability of argon strongly dependent on the feed gas flow rate. Jets driven with pulsed-DC were notably more repeatable than those driven by a high-voltage sinewave. This is attributed to the difference in voltage rise time, which promotes more consistent ignition times. Increasing the voltage and frequency of the pulsed-DC plasma jet can further improve repeatability, where voltages above 2 kV and driving frequencies above 200 Hz significantly enhance the repeatability of the plasma jet.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 12","pages":"5597-5607"},"PeriodicalIF":1.3,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106537","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}
