Following are abstracts of papers from
previous EMC symposia, related conferences, meetings and publications. EMCAB COMMITTEEConsultant r.d.hunter@ieee.com EMC Research Section, Northern Jiatong University, Beijing, China emclab@center.njtu.edu.cn L.E.A.D., Maisons, Alfort France FerdyMayerLEADFrance@compuserve.com Department of Electrical Engineering, University of Rome, Italy sarto@elettrica.ing.uniroma1.it “How Can I Get a Copy of an Abstracted Article?"Engineering college/university libraries, public libraries, company or corporate libraries, National Technical Information Services (NTIS), or the Defense Technical Information Center (DTIC) are all possible sources for copies of abstracted articles of papers. If the library you visit does not own the source document, the librarian can probably request the material or a copy from another library through interlibrary loan, or for a small fee, order it from NTIS or DTIC. Recently it became clear that EMCABs were more timely than publications which were being listed in data files. Therefore, additional information will be included, when available, to assist in obtaining desired articles or papers. Examples are: IEEE, SAE, ISBN, and Library of Congress identification numbers. The abstracts of papers from EMC Japan are now available on the web-site: https://www.tc.knct.ac.jp/EMCJ/index-e.html, which has been provided by the IEICE EMC Japan Technical Committee and the EMC-S Japan Chapter with the aid of Professor Yoshifumi Shimoshio, Kumamoto National College of Technology. Most of the papers are available in Japanese only, while the abstracts are clearly identified. In each abstract the author's address or e-mail is given below the article title. You can directly contact the author(s) of your interested article and request the copy. In case you cannot reach the author(s), please feel free to contact Prof. Shimoshio via e-mail at yshimo@tc.knct.ac.jp . He will assist in routing your request to the author(s), but her will not translate the papers. As the EMC Society becomes more international, we will be adding additional worldwide abstractors who will be reviewing articles and papers in many languages. We will continue to set up these informal cooperation networks to assist members in getting the information or contacting the author(s). We are particularly interested in symposium proceedings which have not been available for review in the past. Thank you for any assistance you can give to expand the EMCS knowledge base. |

Abstract: In this paper some methods to perform integrated circuit (IC)
susceptibility tests are described. The Work Bench Faraday Cage method allows the
measurements of small PCBs or ICs immunity to common mode conducted RF interference, while
the direct injection method makes possible the evaluation of IC immunity to differential
mode disturbance. The evaluation of ICs susceptibility to electromagnetic radiated field
can be performed by the TEM cell method. Test benches related with methods summarized in
this paper were realized and used in order to verify experimentally the immunity of a
micro-controller IC. In this work, the different measurement procedures are compared and
the test benches weak points are highlighted.
Index terms: Susceptibility, immunity, IC, workbench Faraday cage, TEM cell.

Abstract: Power and ground planes are required to have low impedance over a
wide range of frequencies. Parallel ground and power planes in multilayer printed-circuit
boards exhibit multiple resonances that increase the impedance. When rectangular shape of
printed circuit board is not allowed for optimal using of the available physical
dimensions, the cut area can be seen as a discontinuity of the plane. This kind of
discontinuity can decrease the impedance of the plane pair. Simulation based on
transmission line grid model and measurements results are presented for some typical
configurations.
Index terms: Printed circuit board, ground/power planes, discontinuity,
resonance, transmission line grid model.

Abstract: Nonlinear interference and distortions have a profound impact on
wireless communication system operation, especially under conditions of severe
electromagnetic environment (overcrowded spectrum, strong interfering signals, multi-path
and multi-signal environment etc.). In this paper, we propose a new behavioral-level
simulation technique – the "instantaneous" quadrature technique, which can
be employed for the EMC/EMI analysis of wireless systems in a computational-efficient way
taking into account nonlinear effects (over wide dynamic and frequency ranges) and,
secondly, we discuss how to apply the instantaneous quadrature technique to simulate
wireless receivers and transmitters for EMC/EMI problems.
Index terms: Wireless communication, nonlinear interference, nonlinear
distortion, modeling.

Abstract: Electromagnetic topology is a powerful tool to investigate
disturbances in complex systems. It can be used to calculate voltages and currents that
occur on the wiring of a system. However, in this approach so far only uniform
transmission lines are included. In this paper, a method to treat non-uniform transmission
lines in topological networks is presented and some frequently used non-uniform cables are
analyzed. Wiring in a PC housing is investigated and a comparison with measurement,
numerical simulation using a method of moments code and with the results of the
topological method is carried out.
Index terms: Electromagnetic topology, non-uniform transmission line, cable,
wiring, multi-conductor.

Abstract: In a lot of cases the shielding effectiveness of a shielding
structure is determined by apertures that have to be present for different practical
reasons. In order to try to minimize the unwanted coupling between the external
environment and the shielded volume due to the apertures, they are often loaded with
different media. The analysis of the shielding performances of loaded perforated shields
is here presented. The analysis is performed through a suitable formalism in the spectral
domain, which leads to a circuit interpretation of the electromagnetic problem. The
network analysis yields a sort of Wiener-Hopf equation that can be interactively solved
through the method of moments, until the required accuracy is reached. The considered
analytical approach, suitable for any kind of aperture, is validated through an
experimental analysis of a typical configuration of practical interest showing a good
agreement of the measured and predicted data.
Index terms: Shielding, perforated shield, aperture, Wiener-Hopf equation, method
of moments.

Abstract: A simple and accurate model for base station panel antennas is
proposed for dosimetric analysis. A unit cell of the antenna is modeled and is denoted as
the generic model. The field of the entire antenna, denoted as the syntheric model, is
obtained by superposing shifted field contributions of the generic model. Comparison of
the synthetic model with the full antenna modeled and with measurements illustrates the
accuracy of the synthetic model.
Index terms: Base station, panel antenna, radiated field, numerical modeling.

Abstract: In this work, a probabilistic approach for the characterization of
wiring harness susceptibility to external interference is presented. The problem of
field-coupling onto a uniform, two-conductor transmission line is considered by modeling
the external field as a plane wave with random parameters. The probability density
function of the voltage induced in one of the line loads is derived analytically, under a
low-frequency assumption. The proposed model allows computation of statistical parameters
of interest, such as expected values, variances, and confidence intervals of voltages and
currents in the line loads.
Index terms: Transmission line, susceptibility, external field, probabilistic
model.

Abstract: The authors have constructed a prototype feed-through type EMI
filter by filling the hollow portion of a coaxial structure having an outer diameter of 7
mm and an inner diameter of 3.04 mm with composite magnetic material made up of Fe-Si
alloy flakes and polyphenilene sulfide resin. Insertion losses were measured in the
frequency range from 100 MHz to 20 GHz for filter specimens containing different length of
composite magnetic material, and an insertion loss of 10 dB and greater was observed from
1 GHz to 20 GHz in the case of 20 mm. In addition, using material constants of the
composite magnetic material measured beforehand, insertion losses were calculated, and it
was found that the results of calculation agreed relatively well with the above
measurements. On basis of the above, the authors have been able to clarify how the
material constants of the composite magnetic material affect insertion loss.
Index terms: EMI filter, attenuation characteristic, insertion loss, composite
magnetic material, material constant.

Abstract: Norms impose the limitation of electromagnetic radiation of
numerical links between equipment, in the frequency range 100 MHz – 1 GHz. This
radiation is caused mainly by common mode current. This paper describes with the
finite-difference time-domain (FDTD) method the asymmetry of the transmission line created
by different termination for a 15 pin D connector. This asymmetry has a direct impact in
the level of transmission link radiation.
Index terms: Common mode current, transmission link, radiation, asymmetry,
connector, FDTD.

Abstract: RFI power line filters are used to decrease interference in the Main
and provide EMC. For these filters design it is necessary to know the impedance of the
Mains – as a conductive electromagnetic interference receptor (EMI) – and of the
power supply Mains terminals – as an EMI source. Mains impedance may be considered
standard, but switched mode power supply (SMPS) impedance is a problem. The method of
power supply Mains terminal impedance simulation taking into account non-linear nature of
SMPS as EMI source is suggested. In the paper the methodology of RFI-filter design is
suggested to provide filters synthesis for given SMPS, subject to rated parasitic
component's parameters.
Index terms: EMI filter, power supply, power line, impedance, design.
