To improve the reliability of radio electronic devices, engineers use redundancy of the most relevant circuits. The simplest and most common solution is classical cold redundancy in which the primary and redundant circuits are located far from each other. Meanwhile, locating the primary and redundant circuits close together makes it possible to use modal distortions to protect both circuits from unwanted ultra-wideband interference. This approach is known as modal redundancy or modal reservation (MR). This paper presents the results of signal integrity analysis for a structure with single MR before and after failures. It is shown that the bandwidth after failures changes. This affects the rate of data that can be excited to the input of the device without significant distortion of the useful signal. The authors used pseudorandom binary sequences with a data rate of 50 and 200 Mbps. It is experimentally shown that failures in the redundant circuit do not significantly degrade the quality of signal integrity in the bandwidth. Thus, the data-dependent jitter changes from 12 (before failures) to 19 ps (after the worst failure). In all investigated variants, the eye stays open; as a result, the bit error rate will be low. The mismatch of the redundant circuit has the largest effect on the noise amplitude. As a result, the signal-to-noise ratio decreases from 57 (before failures) to 28 (after the worst failure). To confirm the measurements, we performed electrodynamic simulations. Their results are in good agreement with the experimental data.

The 27th IEEE Workshop on Signal and Power Integrity (SPI 2023) was held during May 7-10, 2023, in Aveiro, Portugal, as a joint organization between the Institute of Telecommunications and the University of Aveiro. The IEEE EMC Society was a Technical Co-Sponsor of the Workshop.

With this Personality Profile, I would like to introduce you to Dr. Chaouki Kasmi. Dr. Kasmi is the Chief Researcher at the Directed Energy Research Center at the Technology Innovation Institute (TII), a cutting-edge United Arab Emirates (UAE) based scientific research center. I first met Chaouki Kasmi during a one week course (HPE 201–2011) on High Power Electromagnetics (HPEM) which took place in September 2011 at “Schloss Noer” in Germany. I was a faculty team member and Chaouki was a young Ph.D. student who attended the course. As he was eager for knowledge and due to his personality, Chaouki Kasmi was noticed by the entire faculty team. Since September 2011, Chaouki and I have met frequently at the AmerEM/EuroEM conferences.

The key factors that influence the Radiated Emission (RE) measurement results of Inter Laboratory Comparison (ILC) program, conducted as part of proficiency testing/Quality Assurance of EMC test laboratory are presented in this paper. The evaluated classical Z score results and overall performance of the participant EMC test laboratories in ILC program are affected by these factors. The performance improvement techniques to address the influencing factors and eliminate the deviation in test results of ILC program are outlined in detail. A case study was conducted in the frequency range from 30 MHz to 1 GHz, as the deviation in Z score results is predominant below 1 GHz. The importance of awareness required to conduct ILC program accurately with minimum possible errors is highlighted in this paper.

It is difficult during our present time span to pick up any newspaper or other periodical without finding an article on ecology and/or pollution. Our nation, as well as the entire world, now readily accepts that ecology changes, caused by various types of pollution, are a major crisis.

This is a special issue of the EMC Magazine. It was a joy to work on since there was plenty of banter and good discussion between Mike Violette and Michel Mardiguian. It all started with the last issue of the EMC Magazine, 3rd Quarter 2022, that featured a photo of the Statue of Liberty on the cover and a reference to an article inside on “Lightening Protection of the Statue of Liberty.” Yes, that “Lightening” spelling on the cover was a typo! Several astute readers pointed that out, much to my chagrin. Then, I received an email from Michel expressing doubts about the number of times the Statue of Liberty had been struck by lightning as claimed in Mike's summary of his presentation on the Statue of Liberty given to the Melbourne EMC Chapter. Featured in Chapter Chatter, this once benign column was suddenly the subject of multiple emails back and forth as the calculations were proposed, reviewed, and double checked.
