In this paper, a deep learning-based macro circuit model approach for black-box electromagnetic compatibility (EMC) problems is proposed. The concept of the partial element equivalent circuit (PEEC) method is deployed in constructing the circuit topology in the full-space mesh of a black-box device. The mesh-based circuit model can serve as a powerful tool in solving the emission and immunit...Show More
An investigation on thermally resistant and radio frequency (RF) transparent materials was performed. Thermal stress relaxation tests from 20°C to 150°C showed that polystyrene foam board and polycarbonate demonstrate signs of creep deformation over time. Polyurethane foam demonstrated no thermal stress relaxation. For RF penetrability testing, the 100 MHz to 40 GHz range was studied using an outd...Show More
Frequency-independent relationships for estimating a following number of system parameters of cellular communications under the conditions of multipath propagation of radio waves in urban canyons and the presence of intrasystem interference are obtained: the required equivalent isotropic radiated power (EIRP) of subscriber stations, the maximum data transmission capacity of the uplink radio channe...Show More
In the last few decades, the use of power converters has become essential in the smart grid environment. Consequently, this leads to the presence of a high-level of conducted electromagnetic interference between the smart grid elements. This paper studies the effect of two power converter modulation techniques: conventional fixed-frequency modulation and spread-spectrum modulation, on the performa...Show More
Constantly on-going changes in new technologies applied in modern vehicles introduce many challenges in the automotive electromagnetic compatibility engineering. So far, the currently implemented EMC requirements and methods present sufficient performance. However, they do not illustrate thoroughly an actual automotive environment. They tend to focus on the EMC validation of each syste...Show More

EMC in railways

Electromagnetic compatibility (EMC) must be maintained between the railway infrastructure: OLE, power supply; signalling or train control system; rolling stock and other electrical/electronic systems situated adjacent to the railway, in order to ensure system functionality and safety. In addition all electrical/electronic systems in use on European railway networks must conform with the esse...Show More

EMC in railways

Automotive tests concerning electromagnetic compatibility are usually performed as hardware tests in late development stages. Because the electromagnetic environment in vehicles becomes increasingly complex, changes in these late development stages become more time consuming and financially challenging. In this paper a general calibration method for contactless electromagnetic compatibility analys...Show More
In recent years, with the rapid development of the automotive industry, a large amount of electronic equipment was installed into the car. Due to the space constraints, lots of complex electromagnetic compatibility problems occur caused by the electromagnetic interference between different instruments. Therefore, for GPS navigation equipment installed inside the vehicle, a good electromagnetic com...Show More
In this contribution the authors summarize some aspects of electromagnetic field theory related to studies of electromagnetic compatibility and propose how they can be introduced in lectures in an attractive and interactive way.

Today, railways have numerous communication, navigation, propulsion, power and control systems. These systems are operating in a very limited space resulting in significant interference issues. Therefore, it is crucial to take into the account the Electromagnetic Compatibility (EMC) through the project life time starting in the design stage. This paper presents briefly the EMC manageme...Show More
Recently, IoT and sensor networks have developed rapidly and design for EMC has become challenging. In automotive electronics, V2X technology that enables Advanced Driver Assistance Systems (ADAS) has led to stringent EMC requirements for in-vehicle equipment. Therefore, in addition to noise countermeasure technology, it is becoming important to predict EMC risk. Simulation is an...Show More
Due to the special negative electromagnetic properties, metamaterial has gained wide attention and also been increasingly applied in electromagnetic compatibility (EMC). In the paper, the metamaterial associated EMC design has been addressed through two case studies, one is defected ground structure for common-mode noise inhibition and another is frequency selective surface for the sak...Show More

In this study the simulation method is developed to account for stochasticity effects in multi-cable bundles. When dealing with automotive electromagnetic compatibility (EMC) on embedded electronics, propagation of disturbing signals along wires has a great impact, especially on radiated emission. Cable bundles in automobiles are mostly stochastic and require specific analysis for EM/EMC:...Show More

At present, the electromagnetic compatibility(EMC) high and low voltage coupling network test for automotive electrical sub-assembly(ESA) in the standard only requires the use of an adapter to connect the network and the test sample, in other words, the impedance matching is not considered. In practice, if the impedance does not match, accuracy and consistency of test results cannot be guara...Show More
An IC protected by a transient voltage suppression (TVS) diode may fail if the TVS device does not turn on or does not turn on quickly enough, causing the IC to take the full brunt of the ESD event. System Efficient ESD Design (SEED) simulation can help predict when the TVS will turn on and the level of ESD stress seen by the IC. In the following paper, models are developed to predict the voltage ...Show More

We propose in this paper an efficient method to study electromagnetic wave scattering by thin wires and sheets in 3D. The technique takes into account a conducting wire or a dielectric sheet of complex permittivity by using special finite elements so called « wire element » and « sheet element » respectively. The developed procedure is very convenient to implement in an edge element formulation. T...Show More
