Nowadays, electronic products are being used extensively in many fields and applications. The dense population of electronic devices in human life has become a challenge for microwave engineers to ensure that their products can meet the Electromagnetic Compatibility (EMC) standards. Complex electronic products with smaller sizes and denser components will be a challenge for compliance with EMC standards. In addition, the occurrence of non-stationary emission at certain operating modes becomes a challenge for analysis. Error in analyzing EM emissions will make the products unable to meet the requirements of EMC standards; hence, they will be prohibited to be marketed. Currently, there are two methods of emission analysis, i.e. by measurement and modeling or computation. There are some problems, however, in the analysis of EM emissions regarding the area of test, complexity, DUT positioning error, installation cost, and time consumption. In this paper, the analysis techniques for EM emissions including Open Area Test Site (OATS), Anechoic chamber, Transverse Electromagnetics TEM Cell, Compact Antenna Test Range (CATR) and near field scanning are reviewed comprehensively. This survey covered EMC standards, principles of EM emission measurement techniques, advantages and disadvantages of EM emission measurement techniques, studies and applications of each technique, recommendations for which technique to be used, and challenges for future research in EM emission measurement. The final section of this paper discusses the challenges for near-field measurements related to the non-stationary emissions phenomenon. This papers also presents the challenges of how to detect and characterize them.

Automatic Segmentation of Nonstationary EM Emission of Electronics Product

Characterizing complex and multi-functional devices is a very challenging task. One problem in statistical near field analysis on complex electronic products is the emergence of nonstationary electromagnetic (EM) signals. Such emergence will lead to an incorrect decision if the signal is used as an input to propagation analysis. The most appropriate approach to this problem seems to be one based on the segmentation of the nonstationary time series obtained from measurements into an ensemble of piecewise stationary signals. In this paper, we propose three approaches for automatic segmentation of nonstationary EM emission signals: short-time energy (STE), short-time zero-crossing rate (STZCR), and short-time kurtosis (STK). Test results show that STE is the best in terms of success in segmenting the nonstationary signals to achieve piecewise stationary time series and being less computationally intensive.

“…The article "On the Quality of a Real Open Area Test Site" [11], shows that physical open area test site performance is affected by various factors, e.g., practical elements antennas , the power supply quality, the electric properties of the ground and surrounding scattering sources. The authors employed computer simulations to quantitatively define the effect of all influences that make a real test site diverge from an ideal one.…”

This article presents a set of measurements and simulations that evaluate the technical feasibility of a Compact Open Area Test Site (COATS), for the frequency range of 200 MHz to 2 GHz. Its main goal is to provide shielding effectiveness measurements. The described test setup is used for the tests in both semi anechoic chamber and COATS. These experimental and computational results offer orientations and guidelines about the best method to measure radiated emission in a COATS. These measurements results can be quantified through the Feature Selective Validation technique.
