For an IEMI/HEMP hardened building, external cabling should be enclosed in shield to protect against coupling of high-level transients. The US military standard requires solid conduits, with welded end connections. This paper discusses the use of time domain (transient pulses) laboratory measurements of the protection provided by the cable and connector shielding. Sample results are shown for shielded cables that use non-welded end connections.

To develop usable EBG-based common mode fliters miniaturization is required. In this paper is introduced a quarter-wavelength resonant EBG-based common mode filter on LTCC substrate whose dimensions are miniaturized according a systematic stepped procedure. Results in terms of common mode attenuation and differential mode transmission are presented. Consideration is also given to the decreasing of the direct radiation.

This is a computational electromagnetic study on excessive electric field levels in the vicinity of wearable radio transmitters worn by uniformed personnel. It involves the calculations of theoretical near-field levels at points confined within the zone in-between personnel individual. This analysis is performed using limited computational hardware resources, which is thus reflected in the modelling procedure used.

Ground via design rules may need to be re-visited to support high-speed signaling for 25Gbps and above, according to our experience. In this paper, the study begins with some basic via patterns with different ground via placement to investigate loss, crosstalk, common mode, and electromagnetic field distribution to help understand the underlying physics. The benefit of joint anti-pad is also analyzed for signaling at 25Gbps and above. Impact of adjacent vias to the modeled via pair of interest is studied and it is found that the adjacent vias should be properly terminated and included in the modeling. Finally crosstalk study is performed for the given via patterns.

Electromagnetic analysis in side channel attack exploits the information of electromagnetic radiation that leaks from the cryptographic devices when they are running. It's no-table because of its efficiency and easiness to perform. Correlation electromagnetic analysis (CEMA) is of the most effective means in electromagnetic analysis. However, the efficiency of traditional CEMA is limited by some insignificant' electromagnetic traces. It is necessary to select the helpful subset of the electromagnetic traces for analysis rather than using the whole electromagnetic traces set to improve the efficiency. In this paper, we first give an proposition about the CEMA and prove it by mathematical theory. This proposition illustrates the feasibility of selecting electromagnetic traces. Then we propose a method that is based on Singular Value Decomposition to select electromagnetic traces. This method is adaptive and doesn't need any external parameter. Besides, this method is useful for analyzing both unprotected implementation and masked implementation. We carry out the practical experiments by our SVD-CEMA and CEMA in the same scenario. The experimental results verify that the key-recovery efficiency of our method is higher than CEMA.

In this paper, a novel probe without ground pins is proposed for differential signal measurement. An effective model for the differential probe is built in CST based on measured dimensions. To evaluate the electrical performance of the differential probe, a 4-port measurement is performed for a 1 inch differential pair using the probes. Simulation and measurement results match closely which further verifies the accuracy of the simulation model of both the differential probe and PCB under test. Guidance for launching footprint optimization of the differential probe can be extracted based on the sensitivity analysis results in terms of signal pad size, ground via size and ground pad size of the differential probes. Furthermore, loop inductance of the differential probe is evaluated from both 1-port measurement and simulation results.

With rising frequencies involved in electronics, losses and dispersion exhibited by dielectrics become important to consider in electromagnetic modeling. The Partial Element Equivalent Circuit (PEEC) method is suitable for a mixed electromagnetic and circuit setting, forming equivalent circuits that can be interconnected with circuit elements. In this paper, a descriptor form representation of PEEC models incorporating dispersive and lossy dielectrics is developed. By representing the electrical permittivity with a Debye-Lorentz model equivalent circuits can be synthesized. The synthesized circuits for the permittivity are included in the PEEC equations by formulating the circuit equations for the additional circuit unknowns. This yields an input/output formulation that can handle an arbitrary number of finite dielectrics and be integrated by any kind of integration scheme. Furthermore, it offers a straightforward way to incorporate lossy and dispersive dielectrics into a PEEC solver compared to using recursive convolution. The proposed descriptor form representation is tested for a setup consisting of three microstrips over a ground plane, separated by a dielectric substrate. Both the ideal and the lossy and dispersive case are tested and compared. Furthermore, the proposed formulation is verified against an existing implementation in the frequency-domain. Good agreement between the proposed formulation and the existing frequency-domain PEEC formulation is obtained.

Accurately predicting power supply noise (PSN) induced jitter is crucial to link signal integrity analysis. PSN induced jitter becomes more severe with a decreased supply level, or increased design density. It exhibits strong time dependence due to power management technique employed in low-power design. For the first time, the bursty nature of PSN-induced jitter during power-state transition is accurately accounted for in full-link signal-integrity analysis. We present that power state transition frequency has a major impact on I/O link total jitter. This phenomenon that will be demonstrated with jitter simulations can be utilized to prevent over-design provided architecture-level wake-up behavior is determined.

This paper discusses an approach to analyzing and assessing the frequency spectra of conducted emission profiles due to impulse transients caused by electrically fast transitions. The method discussed is to gauge such a transient's ability to create sufficient energy, high enough in frequency profile, to excite a circuit's resonance. This paper details aspects of the time to frequency domain transformation, key parameters of the circuit that influence this relationship as they relate to CE testing. Discussion of a novel approach is included to allow pre-compliance assessment using the impulse impedance for parallel and series capacitive coupled waveforms. Lastly detailed design considerations and guidelines are given.

Three-dimensional (3-D) integration technique, a promising integration technique, can increase system density but at the cost of increased thermal and power density, leading to thermal-related problems. Design of three-dimensional integrated circuits and systems requires considerations of temperature and gradients observed across the die, because temperature gradients can vary the delay of clock paths. As we need to analyze a large number of parameters for thermal-electrical design, optimization of those parameters becomes important for achieving efficiency and accuracy. Machine learning methods have been applied in the past for artificial intelligence, data analysis, and for general optimization problems. In this paper we propose the application of machine learning methods for parameter optimization in 3-D systems.
