The health effects of EMF on humans are a very topical problem. The Commission of the EU has issued several documents to deal with this matter and CENELEC has set up a technical committee 106x to prepare, together with other committees, relevant product standards. The paper explains the purpose of the EU regulations and gives an overview on the present EMF product standards relating to the limitation of EMF emissions

In this work, a specific box-to-antenna EMI coupling problem in an helicopter platform is investigated. The problem is reduced to an antenna-to-antenna coupling problem by modeling the EMI source with a monopole antenna. The VHF high band blade antenna was chosen as the victim antenna. The effect of the main and tail rotors on the coupling is also considered and the rotor modulation effect on the coupling is analyzed. The investigation consisted of two stages; numerical analysis and scaled model measurements. The analysis and measurement results are compared for both maximum coupling and for different rotor positions. A good agreement is found between the numerical analysis and measurement

An analytic solution to the problem of a plane electromagnetic wave scattering by two parallel elliptic conducting cylinders is presented using an iterative procedure to account for the multiple scattered field between the cylinders. To compute the higher order terms of the scattered fields, the translation addition theorem for Mathieu functions is implemented to express the field scattered by one cylinder in terms of the elliptic coordinate system of the other cylinder to impose the boundary conditions. Scattered field coefficients of various orders are obtained and written in matrix form. Numerical results are obtained for the scattered field in the far zone for different axial ratios, electrical separations and angles of incidence

We propose a new type of optical probe designed to detect magnetic near-fields with high accuracy up to the gigahertz range. The probe head consists of a loop antenna element doubly-loaded with electro-optic crystals. It optically realizes the operation of a conventional doubly-loaded loop probe and requires no metallic cables or hybrid junction. We examined the probe characteristics for magnetic field detection up to 10 GHz. We confirmed that the probe can detect magnetic fields near a microstrip line and suppress the influence of electric fields

In this work, scattering matrix of the constant impedance sphere is investigated by using series expansion of the incident and the scattering field. Using impedance boundary condition, unknown coefficients in the scattering field were found. We consider the there dimensional case as, sphere is illuminated by plane wave that be along z direction. We obtained the general expressions of the scattered field. Then we sought for the scattering matrix for the y-z plane

Cellular phone base stations are often placed in the poles of power transmission lines. We consider the case when such base stations are powered from the low-voltage network. Of special concern is the current that might be led through the cable metallic shields to other customers' premises in case of lightning stroke, which is a frequent cause of flashover of the high-voltage insulators and a subsequent phase to ground fault. This paper presents an analysis in the frequency domain of the lightning current distribution between the earth wires, grounding systems and power cable network, in case of lightning stroke at the tower. The models and the analysis are applied to a practical case

Installations in railway systems represent a classic example of extended, large and complex systems. Controlling and ensuring their electromagnetic compatibility is therefore a challenging task and beyond it a fundamental condition because many aspects of personal safety have to be considered. This paper describes the requirements and problems associated with measures to be undertaken when railway infrastructure has to be modernized. It outlines the procedure for analysis and control of EMC in the case when an electronic interlocking system will be introduced into an existing railway environment replacing an old mechanical or electromechanical system. Criteria will be presented for the performance of EMC analysis. Selected potential interference situations regarding track detection systems will be described

The harness used on any vehicle is unique to that model, having a specific length of wiring to optimize connections between circuits and a unique configuration of signal and power cabling for each model. The international automotive EMC standards, however, all specify specific "standard" lengths for test purposes. While using a standard harness length makes comparison of results easier to perform for different electronic-sub assemblies (ESA) for use on vehicles, does it affect the actual test performance? Presented here is the result of radiated emissions tests conducted to the European automotive EMC directive (95/54/EC) utilising five different "standard" length test harnesses and a wide-band noise source. The results illustrate the differences that the harness length has on this individual test technique and discussion on the implications this may have on final installation is provided

Due to the difficulty of electromagnetic interference (EMI) measurement in an actual pacemaker use situation, the recommendations for the management of health risks of implanted pacemaker users from portable telephones have been developed, based mainly on an in-vitro measuring system with a cuboid liquid phantom simulating a homogeneous human body. The validity of such a highly simplified human body model, however, has never been carefully examined. In this paper, with the application of our previously proposed numerical method for the EMI evaluation of pacemakers by portable telephones, we first confirmed Irnich's finding that the maximum interference distance increases with the third root of the antenna transmitting power for a homogeneous cuboid torso model in order to show the validity of our modeling. We then investigated whether the finding holds true for an actual human body using an anatomically based human model, and confirmed the usefulness of the simple cuboid model in the EMI evaluation for cardiac pacemakers
