IEEE Transactions on Electromagnetic Compatibility | Year: 2014

The growing application of simulation tools to increasingly complex problems makes the use of validation techniques essential to improve confidence in the veracity of those simu-lation results. The feature selective validation (FSV) method is widely used today, because of its versatility and simplicity. However, despite its many advantages, some problems have been identified in the standardized FSV method. Those drawbacks can produce misleading results for the validation process and constitutes enhancement opportunities for further research on FSV improvement. This paper presents a review that summarizes the major problems of the FSV and their possible solutions as a justification to reform the FSV method and also looking towards the forthco-ming update of the standards IEEE 1957.1/2. © 2014 IEEE.

In the past 30 years, the Electromagnetic Compatibility has established itself as one of the most important quality disciplines, supported by both national and international standards and regulations. The increasing technological development of emerging economies of Latin America and their greater participation in the global market has created the need for continued regulation of their production of electrical and electronic devices. Latin America has a significant potential for economic growth not only as a producer of raw material but also as an exporter and importer of technology and in consequence the Electromagnetic Compatibility has an important role to play. This study shows the current status of the region in terms of regulations, standards and testing facilities relating to electromagnetic compatibility, through a comparison between the four Latin American countries with the largest gross domestic product: Argentina, Brazil, Mexico and Venezuela. Finally, a projection was made on the potential future development of this technological area. © 2003-2012 IEEE.

Based upon the standard IEEE 1309, a new calibration method for electromagnetic (EM) probes is proposed. The aforementioned method compares the electric field strength measured with the EM probe subject to calibration with the E-field intensity calculated through a linear interpolation of the corrected measurement using a reference EM probe. The corrected measurement results are computed by means of the calibration factors stated in the calibration certificate of the reference EM probe. The conditions and criteria, under which it is possible to calibrate EM probes inside semi-anechoic chambers in the frequency range of 80MHz to 1 GHz, are presented. The results shows that the calibration method proposed in this paper is characterized by deviations less than 1 dB in almost all the frequencies considered, verifying the reliability of the method. The proposed approach is very useful for registering the measurement drift of EM probes used in EMC testing laboratories.
