This approach represents the dynamics of soil ionization and its effect on the resistance of grounding electrodes, but it has a high computational cost as it requires discretizing the working volume into small cells. This article proposes a new method for representing the soil ionization effect on grounding electrodes in FDTD simulations. The electrode resistance is calculated based on the injected current using a dynamic soil ionization model, considering equipotential surface patterns and analytical expressions of the variation in soil resistivity. The resistance variation is then represented in FDTD by an equivalent radius. The method allows the use of coarse meshes and therefore fast simulations, while still considering the dynamics of soil ionization. Application examples with unipolar and bipolar injected current, single vertical rods of different lengths, and four parallel rods are used to validate the proposed method and compare it with the existing one. Results show good accuracy in all cases and a gain of up to 539 times in computing speed compared to the existing method, proving to be an efficient alternative for representing the phenomenon.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"277-285"},"PeriodicalIF":2.0,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simple second-order filter circuit is designed and optimized first. Then, an ESS with metallic patches and octagonal rings is designed to match the second-order filter circuit under the guidance from circuits to metasurfaces. The ESS performs a nonlinear response for the low-power and high-power incident microwaves. The operating properties of the ESS are generated by the interlayer resonance of nonresonant capacitive patches and inductive octagonal rings. Circuit and full-wave simulations are conducted, respectively, and their results show relatively good consistency. Meanwhile, two ESS prototypes are fabricated, and experiments are conducted under different incident power levels in WR-137 and WR-90 waveguides. According to the simulated and experimental results, the proposed ESS has a wide 1 dB operational band covering 5.8–9.0 GHz for low-power incident wave, and high shielding effectiveness of 22 dB under high-power microwave. Particularly, the maximum SE reaches up to 25.7 dB at 9 GHz.

The limiter's performance is evaluated under high-power microwave induced pulse injection at 2 GHz, with varying pulse widths and a pulse repetition frequency (PRF) of 50 Hz. Destruction of the limiter is observed when the pulse width and input power reach 3 <italic>μ</i>s and 63 dBm, respectively. The failure mechanisms are analyzed in three aspects. First, the thermal distribution of the limiter's microstrip lines is understood through equivalent circuit analysis of the PIN diodes. The characteristics of the limiter across different frequencies are also investigated, with a focus on the power levels of PIN diodes near the limiter's input. Additionally, owing to the observed differences in heat-induced discoloration on the two PIN diodes near the input port, their thermal and stress effects are compared by incorporating temperature boundary conditions and absorbed power in the analysis. Thermal accumulation in the PIN diodes is further explored under a higher PRF of 100 kHz. Finally, the thermal and stress effects on the bonding wire interconnects near the limiter's input are considered. Postmeasurement observations reveal damage to both the bonding wire and the PIN diodes, indicating that the bonding wire fails after the PIN diodes.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"227-236"},"PeriodicalIF":2.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specific to the performance evaluation testing requirements of subsystem-level equipment against the HEMP threat, a miniaturized vertical polarized bounded-wave simulator is designed and developed in this article. Based on the direct drive method wherein a fast compact Marx generator (CMG) discharges to a guided-wave antenna with a codesigned pulse-shaping switch, the developed simulator is capable of generating a standard HEMP radiation environment in a limited test volume and guaranteeing the consistency of peak field intensity with a fixed operation voltage. Integration of a self-steepening structure into the conventional CMG effectively improves the output pulse front edge by modulating the stray capacitance value. Consequently, the primary pulse output with an amplitude exceeding 220 kV and a rising time of less than 4.7 ns can be realized, significantly expanding the dynamic working range of the pulse-shaping switch. Additionally, the integrated design of the pulse-shaping switch and the radiation antenna ensures structure continuity, facilitating the distortionless transmission of the feeding voltage pulse. This modification enables the realization of the rising time of the radiation electric field extending from the standard 2.5 ± 0.5 ns to the subnanosecond range. The simulator can generate an electromagnetic environment with a maximum electric field intensity surpassing 100 kV/m and a field uniformity of 2.8 dB. This article provides a fresh perspective on the design of a compact and reliable bounded-wave HEMP simulator.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"174-190"},"PeriodicalIF":2.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142690665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
