Special Sessions for 2015 International Symposium on EMC 

Special Sessions 

Special sessions are made available to encourage papers on topics and in areas that are beginning to be developed or are of particular interest to the locale of the symposium.  All papers are reviewed to the same technical standard as regular session papers and are frequently organized by one of the EMC Society’s technical or special committees.

Special Session:  Shielding Measurements: From LF to Microwave

Prof. Dr. Ir. Johan Catrysse    
KULab, Technology Campus Oostende

Shielding is one of the design tools in order to comply with both radiated emission and immunity for electronic circuits and systems. Due to the (r)evolution in electronics, shielding at the lower frequencies (below 30 MHz) and at the higher frequencies (up to 40GHz and even higher) becomes an important issue.
Typical new applications that are emanating from the ongoing technology are:
• shielding at lower frequencies, forthcoming from the frequency inverters for automotive applications in e-cars
• shielding requirements up to 40 GHz, due to higher clock frequencies and their harmonics, and also related to the requirements as set by FCC
• shielding requirements at the frequency range of 80 GHz, due to the implementation of anti-collision radar for automotive applications

Not only the enclosures are concerned, but also components such as gaskets and Board Level Shielding (BLS) cans on PCB's.

Insight will be given concerning the measurement setups for the magnetic shielding at the lower frequency range, such as the difference between NSA 65 and IEEE 299.  New setups will be proposed for the characterisation at the µWave range.  The difference in obtained SE results using different measuring setups, with specific focus on non-homogeneous materials will be examined.

Special Session:  EMC Diagnostics of Complex Systems

Vladimir Mordachev
Belarusian State University of Informatics and Radioelectronics (BSUIR)

There are numerous situations where the EM environment is extremely complex with extremely large numbers of RF systems resulting in much unintentional coupling.  These systems may be onboard a ship, aircraft or orbital station and ground-based such as an airport or seaport.

Worst case behavioral modeling of system elements as well as specialized techniques for discrete and non-linear modeling is all needed to EMC analysis and diagnostics.  Papers in this session will cover;

• Behavioral modeling of full complex systems and the elements that compose them. 
• Worst case behavioral models of spurious coupling using highly efficient techniques
• Efficient measurement techniques and computer modeling for the extraction of critical element characterization that is necessary for the full analysis.

Large scale system present extremely complex EMC challenges.  This session will provide insight to methods and techniques that can be used to examine such cases in a practical and logical manner.


Special Session:  EM Information Security and Countermeasures

Dr. Yuichi Hayashi
Tohoku University, JAPAN

In advanced information societies, information leakage and communication disruptions associated with telecommunication devices (equipment and systems) have a strong impact on social and economic activities, and security technology that can ensure the security and reliability of such devices is becoming increasingly important. One of the main reasons for information leakage is unintentional or intentional radiation of EM fields from communication devices. Such radiation, referred to as “EM information leakage”, can even be in the form of weak EM fields emitted from devices that are compliant with existing public standards (e.g., for ergonomic design and radio-frequency interference). This issue requires us to regard EM radiation as “a signal containing information” and to pursue new security assessment and evaluation metrics.

Addressing the above issue, the EM Information Leakage subcommittee of TC-5 presents this special session, which aims to promote and accumulate research on the security of ICT devices, equipment and systems associated with the research field of EMC. In this session, the main targets are cryptographic devices (i.e., electronic devices equipped with cryptographic software/hardware).

Topics in this special session include: acquisition, measurement, and analysis techniques for information leakage from information and communication devices via EM fields; modeling and simulation techniques for evaluation of EM information leakage; countermeasures against attacks based on EM information leakage; and intentional EM interference (IEMI).


Special Session:  EM Field Interaction with Transmission Lines in Different        Environments

Sergey V. Tkachenko, Ph.D.,
Otto-von-Guericke University Magdeburg

Many different kinds of transmission lines, wiring structures, PCB, chip packages, etc. is wide used in modern electrical engineering and electronics. They serve for transmission of signals and energy, in addition to their useful functions they can be subject to the influence of various electromagnetic interference sources, both external and generated by adjacent devices. In this case, these elements work as passive antennas and scatterers.   Moreover, the scattered current can propagate along the transmission lines to the ports of receivers and may enter the sensitive parts of electronics causing failure or even damage of the devices. The frequency range of the interferences can be larger than the working frequency range of the devices. To protect the sensitive electronics from pulse interferences it is useful to calculate the response in the time domain.

These transmission lines are located in various environments: such as above a finite conducting ground, inside the enclosures of different geometrical shapes, and may include some shielding from external electromagnetic interferences. It was shown this circumstance can change the picture of coupling radically.  The problem of the calculation of currents and voltages in transmission lines (with linear or non-linear loads) in complex environments is of great importance in EMC.

Existing numerical methods (Method of Moments, Transmission-Line Matrix Method, etc.) allow considering specific cases only, but do not describe general physical picture of the interaction. On the other hand, classical transmission line approximations for the lines as in free space as well as in resonators are applicable only for a restricted frequency range.  This special session will examine the analytical description, mathematical and numerical approaches to the interaction of high-frequency electromagnetic fields with wire structures in free space and in cavities.


Special Session:  Intentional Electromagnetic Interference (IEMI) Protection of Critical Infrastructures

Dr. Frank Sabath
Bundeswehr Research Institute for Protective Technologies and NBC-Protection, Munster, Germany

The technology and expertise required to construct a disruptive source is becoming more readily available; therefore, Intentional electromagnetic interference (IEMI) poses an increasing threat to electronic systems. The aim of this special session is to present recent findings with regard to IEMI threat characteristics, risk analysis methods, detection of IEMI environments, effective IEMI protection and hardening. The second part of the session provides an overview on results gained in the three European research projects HIPOW, STRUCTURES and SECRET. All of the speakers have been performing research in the IEMI field for many years.

Papers presented will include test methodology and analysis methods.
