Since the advent of motor vehicles, spark ignited internal combustion engines have been used. While the technology involved has changed significantly since the advent, the end goal is to ignite the fuel in the combustion chamber to produce power. This paper examines various ignition systems, their electromagnetic noise characteristic and reception performance as it pertains to these ignition systems

IBIS models are widely used in I/O related signal integrity simulations. This paper points out the problems with the present IBIS model in power integrity related simulations. A new proposal of adding some additional information to the existing IBIS standard to expand its capability in SSN and other power integrity related simulations are introduced. The processes to extract this information from transistor-level Spice model and implement the new proposal in existing IBIS tools are illustrated by using an example in HSPICE. The accuracy of the new proposed model is verified in simulations with nonideal power supply

The operations experiments of disconnect have been given in 220 kV air insulated substation, the conductive signals of electromagnetic interference have been obtained from potential transformer (PT) and capacitance voltage transformer (CVT) and primary analysis has been given. In order to find out the relationship of time-frequency domain and signal energy, Wigner-Ville distribution (WVD) is used to further analysis. The result reveals that the main frequency of the interference signal is mainly connected with parameters of the equipments in the substation and the configuration of the substation, other than disconnect operation time and speed. It is possible to filter the energy of high-frequency caused by disconnect or breaker operation.

In this paper, the wire antenna mounted on an electrically large platform is analyzed. The antenna and its nearby region are modeled using moment method, while other regions are modeled using physical optics. The number of unknowns and computing time are greatly reduced compared with the original moment method. At the same time, we propose a simple model of current expansion for the junction of more than two triangles, which provides accurate and robust results both in moment method and physical optics solutions. Several numerical examples are presented to show the accuracy and efficiency of this hybrid method and the proposed current model.

In this paper, the shielding of an enclosure with contents is described with particular emphasis on the frequency range of above 1 GHz. A statistical approach is taken to account for the complex nature of shielding at these higher frequencies. A measurement set-up is described as used in an anechoic chamber. Numerical simulations based on the transmission-line matrix (TLM) modeling method are also performed in order to complement the experiment work. The work is undertaken to inform the new work on IEEE Std 299. It should be stressed that the work is not finalized and that the purpose of this paper is to report on progress and elicit comment.

In this paper, we present an overview of techniques for meshing EMC and signal or power integrity problems for the PEEC method. For these problems, the geometries usually consist of complex heterogeneous mixed circuit and electromagnetic structures. Hence, these structures include different complex mixed electrical and electromagnetic details unlike, for example, a more homogeneous scattering problem. One of the issues of interest are minimizing the complexity of the meshing while preserving sufficient accuracy. We consider some of the fundamental mixed-problem meshing issues and some of the algorithmic issues which are important for this class of problems when the partial element equivalent circuit approach is applied.

In this paper, the great advantages of a high dielectric constant thin film EBG power distribution network (PDN) for the suppression of power/ground noises and radiated emissions in high-performance multi-layer digital PCBs were experimentally demonstrated. Five-layer test PCBs were fabricated and their self PDN impedance and S/sub 21/ measured. The power plane noises and radiated emissions were measured, investigated and related to the PDN impedance. This successfully demonstrated that the band-gap of the EBG was extended more than three times, covering a range from 300 MHz to 3.6 GHz using feasible EBG cell size (1 cm /spl times/ 1 cm), the power plane noise was reduced greatly over a broadband spectrum including hundreds of MHz range and the radiated emission was suppressed by 22 dB owing to the outstanding noise isolation efficiency of the high dielectric constant thin film EBG PDN.
本文通过实验证明了高介电常数薄膜EBG配电网络(PDN)在抑制高性能多层数字pcb中的功率/地噪声和辐射发射方面的巨大优势。制作了五层测试pcb，测量了其自身PDN阻抗和S/sub 21/。测量、研究了功率平面噪声和辐射发射与PDN阻抗的关系。结果表明，在可行的EBG单元尺寸(1 cm /spl次/ 1 cm)下，EBG的带隙扩展了3倍以上，覆盖范围从300 MHz到3.6 GHz，在数百MHz的宽带频谱范围内，由于高介电常数薄膜EBG PDN出色的噪声隔离效率，功率平面噪声大大降低，辐射发射抑制了22 dB。

The paper presents how it is possible to characterize a current probe in terms of its transfer impedance inside a reverberation chamber. The probe clamps a floating wire placed inside the working volume of the chamber and the current on the wire is calculated from the knowledge of the total average field in the working volume, measured by a tri-axial field sensor. The current is calculated representing the field in terms of a summation of random plane waves, where a FDTD code is used to compute the current induced by each plane wave along the wire clamped by the probe under test. Results for the current distribution along the wire are reported for several frequencies. Finally, the transfer impedance of commercial probes is recovered from the current knowledge and compared to the values given by the manufacturers
