To improve security characterizations, inductive probes need to be optimized as regards the pulse waveform and field distribution. The improvement of these parameters leads to greater electromotive forces generated in the integrated circuits, which reinforces the efficiency of the attacks by fault injections. This paper presents a complete model of the electromagnetic field induced at the target surface according to Biot and Savart's law. This work defines the relevant design parameters of the new probes that are used for hardware characterization of the target components. These new probes reduce the voltage fault threshold required to disturb the execution of a program in the target. This paper also presents results related to the optimization of spatial resolution and inductive power at the target circuit surface. Understanding these phenomena then helps to implement countermeasures and best secure the strategies of the key IC components.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127817683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the method, shielded cables illuminated by electromagnetic fields are represented by the external and internal transmission line models. The two models are coupled by a transfer impedance due to the shielding conductive layer. Furthermore, shielded cables' junctions are specially handled by applying three theorems in both external and internal transmission line models. Moreover, the transmission line models are then integrated into an in-house 3D FDTD solver, JEMS-FDTD, to efficiently model shielded cables with junctions inside electrically large objects. In the end, the proposed hybrid method is validated by assessing the induced effects of a three-conductor shielded cable with junctions inside a vehicle when the illumination is a plane wave excited by a strong Electromagnetic Pulse (EMP) and comparing the results with those obtained from the commercial software.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128450854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments show that the measurement system obtains accurate results and offers new capabilities to deal with the drawbacks that traditional frequency-sweep instrumentation implies. The multitone approach injects signals at the entire frequency range simultaneously. Therefore, the measurement system is able to characterize time-varying and the nonlinear devices.

Reliable sensor data (e.g. Rain, ambient light, tire pressure, Radar, LiDAR, ultrasonic park-assist, etc.) are crucial in safety applications and might be a challenge under the existing and emerging radio fields to avoid systematic failure of the ADAS. The sensor data from some EMI sensitive ADAS sensor might not be reliable under foreseeable intended and unintended use. At that moment it's important to be able to detect the radio field that causes inaccurate/incorrect sensor data. This paper describes an integrated, accurate, frequency flat RF detector with programmable RF-immunity acceptance threshold and state of the art resolution. The EMI-detector is integrated in a Rain & Light-ADAS sensor IC that decides on the activation of the vehicle head lights and wipers. The design of the EMI detector allows to share pin-resources (it reuses the light sensor input pin and allows concurrent operation with the light sensor). To avoid availability issues the RF-immunity acceptance threshold - triggering safe state in this IC - can be programmed above the minimal EMI level for which the ADAS sensor is designed.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115330783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure compliance with the applicable EMC regulations, a wide variety of EMC tests, such as checking compliance with electromagnetic emission limits or ensuring a sufficiently high immunity to interference signals, are performed on integrated circuits (ICs) and electronic systems. In most cases, however, these tests are performed in sequence and each result is evaluated separately. A possible mutual influence of the test procedures is usually not taken into account. In this article, we discuss how radio frequency disturbances can affect the generated electromagnetic emission of an IC. Therefore we propose a simple test method which is based on the direct power injection (DPI) characterization method according to IEC 62132 and the 150-Ohm method according to IEC 61967. We show, how the operating state of ICs is changed by an interference signal, such that electromagnetic emission limits are exceeded and in addition the ICs do not fulfill the functional requirements anymore.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115810818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These requirements result in design restrictions that make it complicated to use basic EMI shielding techniques. Consequently, innovative shielding solutions are needed. Thereby, the board-level shielding (BLS) solutions are widely used in printed circuit board (PCB) applications to reduce the intra-system EMI of integrated circuits (ICs) and improve the immunity of the electronic devices. This contribution focuses on analyzing a magnetic absorber sheet combined with a metal layer as a board-level shield solution. Using this combination is expected to obtain higher shielding effectiveness than using only a magnetic sheet by obtaining the absorbing properties of the magnetic material and the losses mechanism of a metal, such as reflection and eddy current losses. One of the main advantages of using this hybrid structure is that it does not require redesigning the electronics since it can be stuck over the EMI source. Therefore, a magnetic material with different thicknesses is combined with metal layers. These hybrid combinations are compared with the performance of a shielding cabinet in order to determine its performance. The results presented are based on the spectral and spatial magnetic near-field distribution measurement.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127173983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
