By coupling the fluid dynamics equations and the Poisson equation, the negative corona discharge between <italic>a</i> plane and an ellipsoidal electrode is modeled in this article. The mechanism of ring mode discharge is, for the first time, systematically investigated through numerical simulation. The relationship between the mode of first discharge and electrode-plane setup conditions, such as various cathode shapes, applied voltages, and gap distances, is analyzed. The position where ring mode discharge occurs is correlated with the maximal electric field intensity during the discharge, which is generated by a combination of boundary charge and volume charge in the domain. It is found that in some cases, the discharge pulses can all be in ring mode. The first discharge tends to be in ring mode when the absolute value of applied voltage is lower, the semiaxis ratio <inline-formula> <tex-math>$a/b$ </tex-math></inline-formula> is larger, or the gap distance is longer. This study provides important insights for optimizing the design of electrodes and improving the efficiency of discharge in applications such as electrostatic precipitators, plasma devices, aero-engines, and other devices utilizing corona discharge.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 10","pages":"3113-3120"},"PeriodicalIF":1.5,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145289538","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}

To address poor filtering performance, a feed scheme utilizing hybrid substrate integrated waveguide (SIW) and spoof surface plasmon polariton (SSPP) structure is proposed in this article to achieve good wideband filtering performance. To address low gain, first, utilizing loaded corrugated slots technique etches a set of inclined slots on radiator arms to suppress the low-frequency gain drop caused by edge diffraction current. Second, a high effective permittivity double-sided cross stripe metamaterial (DCSM) unit is developed and according to phase calibration theory nonuniformly loaded on the front end of the antenna to achieve wideband gain enhancement. For demonstration, the proposed antenna is fabricated and measured. The measured results show that the fabricated antenna operates at 8.14–12.29 GHz [fractional bandwidth (BW) 40.1%] with an average gain of 9 dBi and a high skirt selectivity of 23.88/21.25 dB/GHz, which verifies the superiority of the proposed antenna.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 10","pages":"3121-3128"},"PeriodicalIF":1.5,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290221","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}

However, these parameters of air from different sources vary and are environment-affected. In the present work, the commonly used IAC data in corona discharge research are compared with the data of air calculated by the Monte Carlo (MC) simulation and the Boltzmann equation with different collision cross sections. The results are significantly influenced by both the collision cross sections and the calculation method, and additionally, the effect of humidity on the results is studied. Subsequently, the corona onset voltage of the wire–plane electrode is predicted by the photoionization criterion and measured in an artificial climate chamber. For the first time, the impact of IAC differences on the prediction of positive corona onset voltage under varying environments is analyzed. Experimental comparisons reveal that the impact is marked, especially under varying humidity conditions, where the impact trends are opposite. To ensure the comprehensiveness of the research, the photon absorption coefficient is also analyzed. Finally, according to the comparisons, recommendations for parameter acquisition methods in positive corona discharge research are provided, which will offer valuable insights for addressing corona discharge issues in various environments.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 10","pages":"3153-3161"},"PeriodicalIF":1.5,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290226","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}
