In this paper we present a method for calculating the conditions necessary to eliminate interference between radio sets of radio links of mobile radio communication systems. These conditions are referred to as the conditions of electromagnetic compatibility (EMC) of radio links. These conditions can be used to provide EMC when designing and operating mobile radio communication systems.

Electro-magnetic fields resulting from a GSM transmitter mounted on a large wind turbine will be analyzed. This cellular system operates as novel communication backup in case the standard communication between operator and hub control systems is interrupted. The method-of-moments is used to analytically describe the electro-magnetic fields caused by a GSM 900 MHz transmitter mounted on the hub of a wind turbine. Using a commercial simulation tool the electromagnetic field distribution will be analyzed to determine an optimized wireless communication link to a base station. Different transmitter positions are evaluated based on their radiation patterns. Scattering and diffraction by the turbine’s rotation is taken into account.

Resulting from high welding currents, resistance welding is accompanied by intense magnetic fields. In the paper, it is demonstrated that field exposure of operators of resistance welding machines can be lowered by means of field compensation, if otherwise exposure limits would be exceeded. The field compensation arrangements are investigated and optimized by finite elements (FEM) simulation and verified by measurements.

The paper aims to present the situation in the regulated field of EMC in Romania, country that lately has made important steps to get close to the actual requirements linked to product quality assurance both for the products intended for the Romanian market and for the exported ones. Due to the transcription in the Romanian legislation of the European Directives and of their application guides, to the translation/endorsement of the main harmonized EMC and Safety standards as well as to the setting up of accredited laboratories and of a market surveillance structure at present in Romania there is the infrastructure and the skilled people necessary to solve the actual requirements. In this way, the free movement of goods and market surveillance are ensured in Romania and to this effect the main operators in EMC field acting on the Romanian market are presented.

A methodology for the evaluation of the total power radiated by a wire in a Reverberation Chamber is proposed. The cavity Green’s function and a probabilistic model for the quality factor are used in order to avoid the simulation of the set cavity/stirrer. The numerical evaluation of the current is carried out starting from a method of moments. Then a stochastic collocation method is proposed for the evaluation of the radiated power average. Results are finally compared to Monte-Carlo simulations.

Grounding basic function as the earth termination of the lightning protection systems is to effectively disperse the lightning current to earth without causing any danger to people or damage to installations. However, due to the inductive phenomena, the grounding performance might be much worse at high frequencies in comparison to low frequencies, which might deteriorate the efficiency of the protection during fast front lightning current pulses. This paper provides simple empirical formula for a first approximation of the impulse efficiency of some common arrangements of vertical and horizontal ground electrodes for typical lightning current waveforms. The effects of the soil ionization are disregarded; therefore, the new formula leads to a conservative estimate of the upper bound of the impulse impedance.

The decrease in normal signal levels, the increase in the operating frequencies, and the use of digital electronics in modern systems have led to the need for heightened EMC considerations, and consequently, better EMC models. A preliminary mathematical model based on neural networks theory is developed for predicting the level of susceptibility of integrated circuits to conducted electromagnetic disturbances such as a sine wave. A good correlation between measured and simulated results is obtained.

In this paper enhancements of parametric behavioral models for the output buffers of digital ICs are explored. A model based on a single-piece structure, which offers improved accuracy in describing state transition events for arbitrary load conditions, is proposed. This model exploits the potentiality of local-linear state-space parametric relations. These relations can be effectively estimated from input-output port responses only, and provide better stability properties and improved efficiency.

The paper analyses the electrical behaviour of real dipole working inside a resonant chamber. In particular, the chamber loading effects on the dipole input impedance and current distribution are investigated by setting a proper EFIE solved applying the MoM . Moreover, a preliminary statistical analysis is accomplished sampling the field when the dipole moves along a trajectory inside the chamber.
