To the best of our knowledge, there are no reported studies on the effect of HPM pulse width and repetition frequency on the autonomous aerial vehicles (AAV) system. The mechanism of the effect of pulse width and repetition frequency on the electromagnetic coupling of electronic systems is unclear. For this reason, this article takes the typical AAV system as the example and investigates the effect of C-band HPM pulse width and repetition frequency on it. HPM irradiation tests on the AAV are carried out and it is found that the GPS receiver, datalink and flight control module are susceptible to be affected and fail to operate normally. In addition, the test results show that the probability of the sensitive device being affected increases with the increase of pulse width and repetition frequency. Moreover, a simulation study of the flight control module subjected to HPM irradiation is conducted and it is found that voltage pulses can be coupled to the cable connected to the flight control circuits, which may affect the normal operation of the circuits. In order to further investigate the mechanism of the effect of pulse width and repetition frequency, an equivalent circuit model is established. It is observed that the voltage across sensitive device loads increases with wider interference signal pulse and higher repetition frequency. This leads to the devices being more susceptible, which is consistent with the test results.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"530-537"},"PeriodicalIF":2.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142643016","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}

This CM-based resonance model, derived from the Poynting theorem, extends its application to accommodate reconfigurable frequency-selective surfaces (RFSSs) by integrating the equivalent circuit of diodes into the impedance matrix of the method of moments. The model not only provides a well-defined physical interpretation with the CMs but also enhances the analysis and design process of FSSs through insightful field perspectives. To illustrate the proposed CM-based resonance model, we exemplify band-stop and band-pass properties using two types of dipole structures, where the substructure impedance matrix transformation is used to account for the interelements coupling. The model is validated through comprehensive full-wave simulation results. Next, a single-layer triband RFSS is further designed with the aid of the formulated model. Prototypes are fabricated and subjected to measurements, revealing good agreement between simulations and experimental results. The confirmed usefulness in guiding the RFSS design of the proposed resonance model is expected to be of potential application in EMI shielding.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"117-127"},"PeriodicalIF":2.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599487","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}

Initially, we delineate the various homogeneous regions within the enclosure. Utilizing the surface equivalence theorem, we replace the interfaces between adjacent regions with appropriate electric and magnetic current densities, adhering to boundary conditions. The resulting surface integral equations (SIEs) are then numerically solved for the unknown current densities using the Galerkin-MoM. This process involves the inversion of a block impedance matrix with relatively modest size and condition number in each block, achieved through a block-inversion technique that significantly reduces computational demands. Notably, there are no restrictions on the number, location, size, or shape of apertures. The method's efficiency and precision are substantiated by comparing the results from several case studies against those obtained using the existing methods in the literature and a commercially available SIE code. It is demonstrated that the shielding effectiveness is profoundly influenced by the operating frequency, loss tangent, wall thickness, and aperture size due to attenuation in the wall thickness, reflections at the wall surfaces, and multiple internal reflections.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"99-107"},"PeriodicalIF":2.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597413","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}

For emerging wireless power transfer systems, this type of exposure is potentially more restrictive than direct exposure. The limits for contact current are prescribed in the international guidelines for human protection from electromagnetic fields, but its rationale is limited compared with that for direct field exposure. In this article, the perceptional threshold for electrostimulation and heating was evaluated based on computational dosimetry from 10 kHz to 10 MHz. First, the time course of the temperature rise was calculated until each subject perceived the contact current. Second, the perception of current was estimated considering the nerve activation modeling. The computationally estimated current threshold for nerve activation was consistent with the measured data at 100 kHz and increased linearly with increasing frequency, which was contrary to the measured threshold for perception above 300 kHz. By contrast, the estimated perceptual temperature increase was smaller at 100 kHz than at 300 kHz and above. These results indicate that the transient frequency of the threshold for stimulation and heating lies between 100 and 300 kHz, supporting the transition frequency of contact current in the international guidelines.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"418-426"},"PeriodicalIF":2.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588502","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}

The near-field distributions in three concerned bands are scanned. The conformal FSS excites slight distortion in the passband but stirs the distributions into a mess, the electric field intensity of which drops by 20 dB in the stopbands. Moreover, the absolute gains in the passband are tested in compact antenna test range. The far-field pattern is also evaluated by near-field to far-field method.
