A 2D-transmission line model for the EM field estimation inside enclosures with apertures
Tập 1 - Trang 424-429 vol.1
The development of efficient phenomenological models which give accurate
estimates for the coupling of electromagnetic energy through apertures and into
enclosures is important for the EMC design of almost all electronic subsystems.
It has been previously shown that a simple analytical transmission line
formulation gives good predictions of the dominant mode TE/sub 10/ as well as
higher-order mode...

Avoiding misleading results of conducted immunity testing on data interfaces of telecommunication equipment
Tập 2 - Trang 907-910 vol.2
Failures during conducted immunity testing can sometimes be eliminated when the
EUT is properly exercised. Much of today's telecommunication equipment possess a
large capacity for interconnections and bandwidth. Support equipment needed for
simulating a telecommunication network is expensive and sometimes unpractical
for testing. Improperly simulating an EUT's intended environment and application

Field coupling to nonuniform transmission lines with linear characteristic impedance
Tập 2 - Trang 621-626 vol.2
In this paper, plane wave field-coupling onto a nonuniform, lossless,
transmission line running over a ground plane is solved analytically by means of
a power series expansion in the longitudinal variable z. A linear variation of
the characteristic impedance versus z is assumed. It is shown via examples that
the obtained analytical results represent the limit solution of the approach
based on the ...

A comparison of reduced-order techniques for complex interconnects modeling
Tập 1 - Trang 457-462 vol.1
This paper compares the performance of different reduced-order modeling
techniques applied to the description of complex interconnect structures. In
particular, we analyze two main classes of modeling tools, the block complex
frequency hopping (BCFH) and the subspace-based state-space system
identification (4SID) techniques. The strong and weak points of both methods are
analyzed with particular a...

A pulse method for measuring the minimum shielding effectiveness of enclosures
Tập 1 - Trang 377-382 vol.1
This paper reports a pulse technique for measuring the shielding effectiveness
(SE) of enclosures, without the use of an anechoic chamber or an open area test
site (OATS). Experimental results are presented and compared to those of the
conventional frequency domain method using an anechoic chamber. The results
obtained from the pulse method are in good agreement with those of the frequency
domain ...

Investigating electromagnetic exposure of communication cables in reverberant chambers
Tập 1 - Trang 233-237 vol.1
As distributed electronic systems become more complex, the electromagnetic
compatibility (EMC) behaviour of the communication cables becomes more
significant. Hence a range of test methods must be developed that will provide
an adequate measure of the cable's interference susceptibility. One such method
is the 'mode stirred reverberation chamber method', which offers a complementary
technique to t...

Shielding performance of multi-layered lossy finite length dielectric cylinders at oblique incidence
Tập 2 - Trang 851-854 vol.2
This paper gives a general electromagnetic formulation of the absorption
properties of multi-layered cylindrical enclosures at RF frequencies and above.
The formulation has no limitations concerning frequency. Thus very low
frequencies are also considered for comparison with the results in literature.
The enclosures considered here are lossy dielectric as well as metallic.
Analysis has been made f...

The complex antenna factor of broadband, wire-cage biconical dipoles
Tập 1 - Trang 49-54 vol.1
Previous studies on wire-cage biconical dipoles including "calculable" biconical
dipoles have considered only the scalar antenna factor. The complex antenna
factor (CAF) allows determination of both amplitude and phase information for
the incident field and is necessary for the recovery of nonsinusoidal waveforms
from measured data. Here we present numerical simulations of the complex
effective le...
