For two orthogonal polarizations, the cases of parallel and perpendicular orientation of the plane of incidence of waves on the external gratings of conductors are considered. It is found that in the case of parallel orientation of the plane of incidence and when the electric field vector of the incident wave is located in the plane of incidence, the quality (Q) factor of the half-wave resonance first falls to a minimum when approaching the Brewster angle upon an increase in angle of incidence φ, and then increases, tending to the own Q factor of the resonator at φ → 90°. In the case of the perpendicular orientation of the plane of incidence, but when the electric field vector is orthogonal to this plane, the Q factor of the half-wave resonance increases constantly with increasing angle φ, also tending to its own Q factor at φ → 90°. Frequency shifts are investigated for “strong,” “medium,” and “weak” coupling of the resonator with the external space. For these cases, a nonmonotonic behavior of the polarization decoupling of the resonator-polarizer with increasing angle of incidence in two orthogonal planes is demonstrated.","PeriodicalId":783,"journal":{"name":"Technical Physics","volume":"71 6","pages":"374 - 382"},"PeriodicalIF":0.4,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336741","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 overcome security issues, the nano digital circuits exhibit greater strength than the traditional CMOS security methods. An advanced nano technology of Quantum dot Cellular Automata (QCA) based hardware security is domineering in this era that rising a greater cyber security from a threat and safeguarding sensitive data within ICs. In this work, the QCA based Enhanced Majority Voter (EMV) gate is presented in a logic locking technique to enhance its security by reducing complexity. In this proposed method, the EMV is performed and execute the correct key only when the exact key is given. This process can be highly safeguarded from thwarting tampering and reverse engineering attempts. The validation result of proposed EMV logic locking revealed as a marginal increase in complexity (measured by dots) that is compared to benchmarks while preserving identical execution times. Therefore, this proposed EMV locking strengthens hardware security without compromising circuit performance.","PeriodicalId":783,"journal":{"name":"Technical Physics","volume":"71 6","pages":"461 - 469"},"PeriodicalIF":0.4,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336756","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 has been shown that the torch shape in direct-flow and vortex plasmatrons sets a law of adding a tempering coal−air mixture to the high-temperature zone. Based on a developed analytical model that takes into account the torch geometry and the kinetics of thermodynamic transformations, the quantitative dependences of the gas phase temperature and degree of carbon gasification on flow swirl parameters and pulverized coal concentration have been derived. It has been shown experimentally that the vortex plasmatron, which forms a cardioid torch with a developed contact surface, makes it possible to achieve stable burning at a carbon dust concentration of 0.6 kg/kg and a power of 120 kW. Under such conditions, the degree of carbon drop increases by 20–25% compared with the direct-flow design at a comparable power consumption. Presented results may serve as a basis for optimizing fuel plasma systems intended for low-grade coal burning.","PeriodicalId":783,"journal":{"name":"Technical Physics","volume":"71 6","pages":"368 - 373"},"PeriodicalIF":0.4,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336749","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}

Parameterization is based on a system of fundamental equations (SFE) for the mechanics of heterogeneous liquids, including equations of state for density and Gibbs potential. State-of-the-art experimental techniques are described. The analysis includes flow structures across varying density ratios, kinetic energy, and potential surface energy (PSE) of the drop. Several coalescence regimes are identified, including intrusive, impact (with drop disintegration into filaments), and an intermediate regime of levitation and rebound. In the intrusive regime, a smoothly inflowing drop forms a coherent volume. In the impact regime, ligaments—thin filaments containing matter from the two media—form at the impact spot. These filaments pierce the base and walls of the cavity, spread across the liquid surface, and are ejected into the air. Fibrous traces of ligaments form ruled and reticular structures on the surface and within the bulk of the liquid. In the intermediate regime, a drop may hover, make contact, partially coalesce, and then rebound with m ass loss. The evolution of gas cavities and bubbles is traced, and the parameters of acoustic packets in external fields are determined. The study emphasizes the need to account for various energy transfer mechanisms—both macroscopic (flows, waves, vortices) and microscopic (dissipative and conversive)—when describing the dynamics and acoustics of drop flows.","PeriodicalId":783,"journal":{"name":"Technical Physics","volume":"71 6","pages":"391 - 413"},"PeriodicalIF":0.4,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336743","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}
