This article focuses on the derivation of emission limits at frequencies above 1GHz. Starting from the technical specification of new radio services as 5G, the wanted and the interference signals at the receiver are calculated for FR1. An alternative model based on power limits is introduced. To show the possible interference of modern equipment a 10 Gbit network was built up using Gigabit switches together with corresponding computers with Gbit network cards and was experimentally investigated in a FAR and RC. The performance of the different measurement environments at the higher frequencies was compared.

A comparison between crosstalk measurement techniques is made to investigate their applicability and efficiency for determining crosstalk between cables above a ground plane made of copper or carbon-fibre reinforced plastic (CFRP). Cost effectiveness, accuracy, speed and complexity of the methods are evaluated. All measurements are performed on two PCBs containing two pairs of copper traces. The techniques that are considered include balanced Vector Network Analyzer (VNA) measurements, balanced Spectrum Analyzer (SA) measurements, balanced EMI receiver (EMI-R) measurements, single-ended VNA measurements converted to mixed-mode S-parameters, and finally measurements with a signal generator (SG) and an oscilloscope (OSC). For verification, measured results are also compared to three simulation techniques, involving a Method of Moments simulation and two different transmission line models.

As the technology continues scaling down and the data rate is increasing dramatically, PCB design has become more challenging than ever. Keeping track of signal and power integrity becomes a requirement for PCB designers in order to meet the product development time and reduce the overall cost. In high speed IO signals, vias play a critical role for the signal integrity quality. It is important to design the via impedance within a certain range. Due to server products have a higher thickness of PCB design than other consumer products, and its data rates are on the cutting edge, the need for the via optimization is acquired. In this work, the investigate on the via impedance control is studied to optimize the via design on the pitch, individual and oval antipad shapes. And the further analyses of via design parameters are examined to understand the effects of dominance.

Reproducibility of radiated disturbance measurements is influenced by the line impedance of the power source used for EUT. A VHF-LISN was proposed to solve this issue. A VHF-LISN can define line impedance so as to avoid such influences caused by different line impedances for connection points at different test sites. At present, two proposed types of VHF-LISN - balanced termination and unbalanced termination - are being considered for implementation in CISPR 16 basic measurement standards. Round robin testing was conducted to investigate the effectiveness of improving reproducibility of radiated emission measurement with two types of VHF-LISN, using a versatile comb generator having two signal source modes, common mode (CM) and differential mode (DM), and by using both 2-wire and 3-wire AC mains cable respectively. CMAD termination was provided as an option. The testing concluded that reproducibility between test sites was improved by VHF-LISN termination for both CM and DM emission sources with CMAD termination effectiveness proving to be limited in the case of 2-wire mains cable being used in CM signal source measurements.

This paper presents a novel approach for the calculation of the transient impedance of the horizontal electrode used as a synchronous generator grounding. When a short circuit occurs in the network, corresponding short-circuit current acts as an excitation source of the horizontal grounding electrode. Both short-circuit current and horizontal electrode impulse response, are defined in the time domain in a closed form representation. Transient impedance calculation is based on the novel derivation of the closed form time domain solution for short-current excitation. Some illustrative numerical results are provided, taking into account various parameters of the grounding system.

Electrification of the drivetrain in modern vehicles brings new problems to the front line. High power electronics, high capacity high voltage batteries and electric machines with vast power density are now common attributes for vehicles. Existing low voltage (LV) on-board power network was extended with a high voltage (HV) drivetrain, which made a great impact on electromagnetic compatibility compliance testing. Low voltage supply conducted and radiated emission limits were adapted by to fit new emissions with their much higher amplitudes. In order to fulfill new limits for HV systems the drivetrain must be fully shielded. Due to construction restrains, an application of a shield around the electric shaft of the powertrain is not feasible. Existing magnetic field inside the stator and insulation breakdowns inside of the bearings make coupling to the shaft very effective, which is resulting in undesirable shaft currents. Hence the drivetrain must comply with defined limits for the electromagnetic compatibility of low voltage on-board power systems. In order to comply, the coupling path between HV side and the shaft of the machine should fulfill the limits for coupling attenuation defined in the international standard International Special Committee on Radio Interference 25 (CISPR 25) [1]. This publication describes a method to obtain coupling attenuation of the machine in the operating state and presents results compared with the corresponding limits described in CISPR 25.

Results of experimental verification of the proposed analytical technique for calculation of the average electromagnetic background (EMB) intensity created by base stations of cellular communications, which is based on estimation of the average electromagnetic loading on area (EMLA) created by base stations, are presented. This verification is executed by comparison of the published results of measurements of levels of EMB generated by 2G/3G radio networks in more than 30 countries, with the results of corresponding analytical worst-case estimations of EMLA and average EMB intensity for the real and potential places of EMB measurements. Results of this comparison convincingly confirm the adequacy of the offered analytical technique for worst-case estimation of EMB created by mobile (cellular) communications, and also support its real practical importance for an assessment of electromagnetic ecology of various areas, electromagnetic safety of population and intersystem EMC in conditions of extremely fast development of radio networks and services of 4G/5G/6G.

Public exposure to electromagnetic fields in the environment has been steadily increasing as the development and application of various wireless technologies, especially the coming of the 5G era. The growing concern about the possible consequent health risks prompts many organizations to conduct relevant studies and set limits to the exposure levels. The spatial distributions of the electromagnetic environment become very important data. The aim of this paper is to investigate the radio-frequency electromagnetic environment in Beijing by measuring the electromagnetic field levels of three representative downtown areas from 10 MHz to 8.0 GHz. The spatial distributions of the electromagnetic field in measured areas are illustrated as two-dimensional maps through interpolation techniques. These results are analyzed with reference to the exposure level limits in China and the official annual report of the national radiation environment.

Characterization of the electromagnetic field emitted by various sources (antenna, radar) is an important issue, either for civil or defense applications. The measurement of the electromagnetic field may be performed by a local probe, the infrared thermography imaging being an alternative way. The latter method, called EMIR [1] (ElectroMagnetic InfraRed) has been used for years at ONERA where it had been developed. We have recently successfully implemented this technique in the domain of visible light, named as EMVI [2] (ElectroMagnetic Visible Imaging). As in EMIR, a thin film (sensitive to either electric field or magnetic field) is heated by the emitted field. But here the film is coated with a polymer doped with fluorescent molecules. As the fluorescent emission depends on the temperature of the film, we achieve a novel thermofluorescent sensor. The results presented here illustrate that new method: both magnetic and electric field imaging of two different radiating systems
