In this quarter's issue, we'll share an overview of the recently selected 2026 EMC Society Young Professionals Ambassadors. Throughout 2026, these YP Ambassadors will be delivering presentations they've prepared, mostly virtual (online) but also in person at local Chapters if feasible, and also spreading the word to Young Professionals everywhere about the EMC Society and our mission. We wish the YP Ambassadors a successful year of representing our YP community and sharing their knowledge with us all!
The 2026 Asia-Pacific International Symposium and Exhibition on Electromagnetic Compatibility (APEMC 2026) was successfully held from 4 to 7 May 2026 at the Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur, Malaysia. It brought together researchers, engineers, practitioners, industry representatives, and students from around the world to exchange recent advances in electromagnetic compatibility, signal and power integrity, electromagnetic environment, EMC measurement, EMC protection, and emerging EMC technologies. It also marked a significant milestone in the history of the APEMC series, as it was hosted in Malaysia for the first time. This arrangement reflected the close professional ties between the two neighbouring countries and further strengthened regional engagement within the global EMC community. The IEEE EMC Society Singapore Chapter led the organization of APEMC 2026 in collaboration with the IEEE RFID Malaysia Chapter, with strong support from the APEMC advisory and steering committees, the IEEE EMC Society, and many dedicated volunteers.
Three hundred and fifty kilometers northwest of Singapore is Kuala Lumpur, the capital city of Malaysia, where the 2026 edition of the Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC) was held from May 4 to 7, 2026. The 2026 APEMC carried special significance as it marked an important milestone in the history of APEMC. APEMC was initiated in February 2006 in Singapore, where the representatives and chairpersons from the Asia-Pacific region decided to hold a unified Asia-Pacific International Symposium on EMC across the region. Ever since then, APEMC has been steadily shaping EMC evolution in the Asia-Pacific region and beyond over the past two decades.
Addressing EMC challenges as early as possible in a product's design process reduces development costs and makes resolving them easier. Preparing a document that specifies the required EMC tests, along with considerations and rules for each section or subsystem entitled (EMC planning), greatly helps in resolving EMC issues and reducing product development costs. In this article, an AAU (Active Antenna Unit) used in 5G network is selected as a complex system containing multiple subsystems and various signal types, serving as a modern, cutting-edge example for practi cing EMC planning. Therefore, this article first introduces the AAU and its subsystems and lists the corresponding EMC standards. Then, each standard is mapped to the sub-system associated with the AAU.
The 2x-thru de-embedding technique is widely used for high-speed interconnect characterization but is prone to truncation effects due to finite measurement bandwidth, leading to high-frequency inaccuracies. This application note introduces autoregressive (AR) extrapolation to extend S-parameters prior to de-embedding, using a simple least-squares formulation. Results from simulated and measured examples show that the method effectively removes high-frequency anomalies and improves accuracy. The approach is computationally efficient and can be readily integrated into existing 2x-thru workflows to enhance de-embedding reliability. A Python-based implementation is also provided for ease of application.
A comprehensive study analysis of inter laboratory for evaluation of reproducibility for EMC emission test, conducted between November 2021 and January 2024 are presented in this paper. A total of fourteen accredited EMC test laboratories had participated in this inter laboratory study. A total of four emission tests namely Conducted, Radiated, Harmonic and Flicker emission tests were investigated in this study and verified the test results between the test laboratories are to be a highly reproducible and adequate for determining the test method is capable of producing identical results. The identified main causes for non-reproducibility of test results in our previous case study are corrected and applied in this inter laboratory study to obtain less than 10% differences in test results between 48 individual test participants.
Closely spaced RFID tags have strong electromagnetic coupling giving rise to significant mutual coupling effects. This may often lead to either performance degradation of the RFID communication or its complete failure. In this paper, the effect of electromagnetic coupling is investigated between a pair of passive UHF RFID tags under various separation and orientation conditions. The investigations are based on simulation as well as experiments. The results reveal that closely coupled tags not only change the resonant frequency of the tags but also degrade the performance of the RFID communication system. However, it is found that by suitably choosing the separation and orientation of the tags the effects of electromagnetic coupling can be minimized.
The “Armour Conferences” were a series of Radio Interference Conferences held in the Chicago, Illinois area from 1954 to 1964. Initially, they were sponsored by the United States Military Services and organized by the Armour Research Foundation.
Greetings, YP readers! I hope your 2026 is off to a great start. Our EMC Society YP volunteers have been busy finalizing the details for our major events this year. In fact, 2026 will be the first year we hold YP events at all three major conferences sponsored by our Society: APEMC, the EMC+SIPI Symposium, and EMC Europe. If you're a YP and plan to attend one (or more) of these events, don't forget to sign up and seize the opportunity to meet other YPs. Relationships formed within the EMC Society can lead to future collaborations and provide valuable contacts when you need a friend to bounce ideas off.
It is certainly a pleasure to be here to speak on this occasion. It is difficult to keynote or say something meaningful at a meeting like this, where the audience knows as much—or more—about the history and background of this field than I do.
The Society's governing documents are periodically reviewed by Society leadership in coordination with IEEE. The most recent prior update was completed in 2018. As part of the Society's IEEE review this year, a comprehensive review of all Society documentation, including the Society Constitution and Bylaws, was conducted in close cooperation with IEEE.
Educating the next generation of EMC engineers is one of the core missions of the EMC Society. The John Howard Memorial EMC Education grant was created with that mission in mind. This grant provides up to $10,000 over two years for activities and investments which improve educational opportunities in the area of EMC.

This book is an excellent advanced reference for engineers working on highspeed digital design and signal integrity. It combines rigorous theory with a strong practical focus and uses clear visual explanations to connect electromagnetic concepts to the real challenges of multigigabit systems.
Faraday shields are used to confine high frequency electromagnetic fields generated by sources such as switching electronics. Here, a simple cylindrical model of a Faraday shield is used to explain why such shields can be compromised by one or more conductors that penetrate through holes in the shield. It is shown that electromagnetic fields within the shield are reflected many times and that the energy carried by the fields exits via the penetration periodically in small amounts over time and may become electromagnetic interference (EMI). The fields inside the shield are enhanced at resonant frequencies within the shield and these resonances are reflected in the fields that escape and become EMI. In cases for which filtering of these exit ports are not practical, it is shown that placing absorbing material within the shield can reduce the energy that escapes and hence the EMI.
The EMC Society launched in 2022 a new publication, the IEEE Transactions on Signal and Power Integrity, co-sponsored by MTTS, CEDA, and EP-S, and led by the Editor-in-Chief Prof. Jun Fan. This journal is the perfect location for hosting scientific and research papers addressing all aspects of signal and power integrity of an electronic system and its components, ranging from integrated circuits and packages to PCBs, from cables and connectors to microelectronic components. Moreover, the latest advancements in the theory, algorithms, design approaches and modeling for ensuring the fidelity and performance of digital, analog, and hybrid electronic systems and sub-systems are the main subjects appearing in the papers published in the past three years.
The use of wireless power transfer (WPT) for charging consumer electronics has grown in recent years, owing to its convenience. The growing adoption of WPT in professional and home healthcare environments is raising concerns about the potential risks of interference with medical devices. Due to inadequate information regarding the emission characteristics of commercially available WPT systems, the electromagnetic (EM) immunity test protocols of many current applicable consensus standards to medical devices have not been evaluated for their appropriateness in assessing interference caused by such WPT systems. To address this critical knowledge gap, we present emission measurements for 13 different inductive consumer WPT devices in the frequency range of 100 kHz to 400 kHz.
The IEEE Wireless Power Technology Conference and Expo (WPTCE) is the world's largest and most prestigious event dedicated to wireless power transfer (WPT). As an annual event rotating among North America, Europe, and Asia-Pacific, WPTCE serves as the central hub for the latest breakthroughs and collaborations in the WPT ecosystem. The conference brings together the global community of engineers, researchers, and industry leaders advancing the future of wireless power. WPT is enabling a true technological revolution powering electric vehicles in motion, energizing biomedical implants and flying devices, and even harvesting solar energy from space.
