EMC performance of an appliance is not only a sign of regulatory compliance and also a sign of the quality of the appliance at the same time. Since the number of appliances and the electronics used in these appliances is increasing rapidly, achieving regulatory compliances and company specific quality specifications are becoming very hard for high volume appliance manufacturer. When the concern is household appliances: Traditional home appliances are characterized with their electromechanical components for EMC. Recently the increase in complexity of appliance control accompanying ever increasing yearly production numbers per site had necessitated the need to look for better methodology for EMC management and control. In this paper the EMC experiences together with the accomplishments of a home appliance manufacturer envisioning a major world player in this sector will be presented. Emphasis is given to the fact that incorporating more electronic control in home appliances at high production volumes makes EMC more of a quality issue than a regulatory issue. Operational changes for EMC management should the company go through to accomplish the high level of quality through EMC

Transmission of high-speed digital video, at large distances, between camera and signal processing unit is a high concerned topic, especially in military applications, where high integrity is required. In our system a number of transmission methods where examined, for a 7 meters video path that includes a number of discontinuities. Finally LVDS channel link method was selected. This paper will present the analysis and simulations performed in order to gain confidence on the design. The simulations performed led to appropriate design and selection of the transmission media (printed flat cables, printed circuits, cables), the interconnections (connectors) and even of the design (repeaters added). The simulation used IBIS model of the drivers and receivers. For the connectors, the printed flat cable and the wiring cable a model was generated based on the physical layout of the elements. This paper will present the whole transmission path, the analysis and simulations performed and the interactive process that led to a closed system configuration and devices selection

Weighting of interference for its effect on modern digital radiocommunication systems is vital for the future definition of emission limits. The effect on radiocommunication services depends on the type of interference (e.g. broadband or narrowband, pulse rate etc.). Starting with the classical concept of pulse weighting to analog radio systems defined in CISPR standards, the paper gives a concept for the definition of weighting of interference to digital radiocommunication systems and experimental results of weighting curves. The results are analysed with respect to their common response and shape. Finally, a detector is proposed for universal application

In this paper design and realization of an L-band helical antenna is presented. This paper describes how to produce a helical antenna for frequencies around 1.8 GHz and presents some characteristics of the antenna found experimentally. Design parameters have been calculated by using standard formulation. For maximizing performance of the helical antenna, attention was focused on such important parameters as the beamwidth, the gain, the impedance and the axial ratio

Three-branch antenna diversity systems using various monopoles printed on wireless devices are demonstrated. The antenna elements used are the inverted F, the Koch and the Minkowski monopole. Computed results for the return losses and the radiation patterns are presented. The calculated envelope cross correlation and mean effective gain of the antennas satisfy the criteria for achieving good diversity performance. The impact of the mutual coupling between the antenna elements on their radiation efficiency and mean effective gain is also addressed

Double bulk current injection (DBCI) method has been proposed to reproduce the same current injection obtained in the case of an electromagnetic coupling with an incident plane wave. Good correlation can be obtained between this DBCI method and the stripline method, and also between DBCI and anechoic chamber methods. But there is no simultaneous correlation between these three methods because the stripline and the anechoic chamber methods are not based on the same coupling modes. This paper proposes a new harness setup conserving the standard harness length of 1 metre, in order to obtain a good correlation between all three test methods. The experimental validation given in this paper shows very encouraging results

In order to simulate the emission of PCBs (printed circuit boards) it is necessary to describe the RF-(radio-frequency)-sources very exactly in a wide frequency range. Due to internal switching of VLSIs a lot of RF-noise can be seen on their supply-pins. These currents I(f) are dependent on the relationship between the impedance Z(f) of the supply-system of the VLSI and Z(f) into the supply-system of the PCB at the supply-pins of the VLSI. This paper describes an effective method to measure both Z(f) and I(f) of the VLSI and compares it to extraction of Z(f) from the VLSI's geometrical data

The finite difference time-domain (FDTD) method was used to study the nuclear electromagnetic pulse (NEMP) waves and the continuous sinusoidal wave of different frequency coupling into one metallic container through a small aperture in one face of the container. The incident electric fields of NEMP were expressed by double exponential functions with two different decay constants. Based on the algorithm of thin material sheets in the FDTD method, the finite-difference expressions of the electromagnetic components at the common boundary of two thin sheets are dealt with distinguishingly. A method to compute the shielding effectiveness of the metal enclosure with an aperture and thin walls is introduced. The time-domain behavior of the electric field inside the metallic container excited by the waves was obtained by the FDTD method. The results of FDTD and ETL method are compared in order to verify the validity of FDTD modeling

In this study shielding effectiveness of a rectangular cavity with a rectangular aperture was examined. Electromagnetic shielding is frequently needed to improve the immunity of electronic equipments. The performance of such an enclosure is determined by its shielding effectiveness. Electric and magnetic shielding effectiveness can be calculated as a function of enclosure dimensions, frequency, wall thickness and position within the enclosure. Another important parameter is apertures which negatively affect the shielding problem. Penetration through apertures is undesirable since it lowers the quality of shielding. Electric and magnetic shielding effectiveness were calculated and simulated both at a microwave frequency band and at a specific frequency value

The evaluation of electromagnetic effects down to the level of pin voltages on a complete air vehicle requires the integration of a number of normally disjoint tools. System CAD geometry is simplified and processed to create a numerical model for solution by a 3D FDTD Maxwell's equations solver. The 3D solution supplies the currents used as the sources for shielded multi-conductor transmission line simulations. Individual conductor terminations at box interfaces are used to obtain pin voltages from the transmission line simulations for detailed effects evaluations. Procedures used to automate the integration process and lessons learned are described
