In this paper, the modeling and simulation of the electromagnetic environment of shipboard equipment is studied. The electromagnetic environment simulation of the ship is carried out on the basis of establishing the sea surface and the ship model and under the different electromagnetic physical quantity. Sea and ship models will be drawn by CAD software, obtaining the electromagnetic simulation results...
This paper presents the implications of the new low frequency radiated emission requirements and how they have been stated for the Solar Orbiter mission so the impact in the design, verification and testing process for the Antenna Pointing Subsystem for the Solar Orbiter and future space missions. The control of Low Frequency Radiated Emission (E-field and H-field) is getting more importance in the...
It is well known that wideband electromagnetic noise is caused by ESD (electro-static discharge) events. Especially, the micro gap ESD of less than 1 kV produces the impulsive electromagnetic noise up to GHz bandwidth. The ESD noise is menace to cause malfunction of high-tech electrical equipment and systems. Then, the impulsive electromagnetic noise caused by the ESD was examined to clear the radiation...
This paper presents a calibration method allowing to quantify the quality of the electromagnetic field generated in a reverberation chamber. The method requires only to measure the reflection coefficient of an antenna (i.e. S11) for different stirring conditions (i.e. different positions of a mode stirrer for a mechanically stirred chamber). The proposed method requiring a simple measurement setup...
Undesired EM radiation generated by wired systems using a PLC transmission, for example, can be a source of EM pollution and bring an annoying problem of electromagnetic compatibility. The evaluation of these near-field radiation is therefore of interest. In this paper, we propose a simplified approach of electromagnetic fields in order to adequately estimate the EM radiation emitted by the wired...
This paper presents an analytical method to determine the electric field inside an enclosure with an aperture from a thin wire as an efficient source outside the enclosure. In this regard, the wire is divided into multiple segments as discrete plane wave (far-field) sources. These sources radiate and excite the enclosure through the aperture which can be modeled by Robinson's formulation. Finally...
The risk of malfunction of cardiac implant due to the influence of external electromagnetic field has been highlighted by the 2013/35/EU European Directive, which classified implanted workers as workers at particular risk. We propose in this study a new method to test in vitro cardiac implants with an electric field of 50 Hz. The exposure system was designed using numerical simulations and does not...
A telecommunication equipment and information technical equipment usually produce unintentional electromagnetic fields. Information from a video display unit could be reconstructed by intercepting such emissions at a distance. The testing methods and countermeasure methods have been discussed and those standardizations have been published at ITU-T SG5 WP2, and ITU-T K.115: Mitigation methods against...
The nature of the Power Line Communication (PLC) equipment is complex because it is considered as an information equipment for Electro-Magnetic Compatibility (EMC) standardization, but it is used to inject High-Frequency (HF) and Very High Frequency (VHF) frequency signals on the existing power network which is not designed to guide these frequencies. This PLC system issue leads to some difficulty...

The main stages of the modeling process are discussed. A simulation approach based on the combination of computationally efficient methods such as surface integral...
The novel volume integral equation (VIE) method was developed for an accurate analysis of low frequency (LF) electromagnetic (EM) fields induced inside human body voxel model. To improve stability of LF solutions, we introduced two sets of unknowns: electric voluminous currents and surface charges defined on interfaces between different materials. At low frequencies, an efficient version of VIE was...

The main goal of this thesis is to enhance SAR method validation of radio military exposure near high power antennas. It will permit to reduce cost and delay of SAR validation and quantify the actual...

Modern radar and communication systems used in ground and naval defense platforms can generate high-intensity electromagnetic field. This high-intensity electric field levels may be hazardous to both personnel and ordnance. Sensitive circuits inside the ordnance may be damaged and also, electrically initiated devices can be activated unintentionally. Thus, ordnance should be immune against high level...

Electromagnetic compatibility (EMC) is vital for health and more reliable electric and electronics systems. All electronic devices have to provide EMC tests. In order to increase the quality of service of all electronic devices, a shielding mechanism has to be provided in order to eliminate electromagnetic interference (EMI). In this study a multi-slits shielding mechanism is proposed by using Uniform...

CISPR25 test is used to characterize EMC performance of automotive component. To avoid miss detection of unwanted emission in this test, it is necessary to scan the measurement antenna along the wire. In this paper, we propose a no scanning method using two loop antennas placed near DUT and wire terminal. Simulation and measurement show that the proposed method picks up unwanted signal with the errors...
